WHAT IS HTML?

HTML stands for HyperText Markup Language. A markup language is a way to write down information with embedded instructions that tell a computer how to interpret and display that information. HTML contains the important information for stucture of the content of a webpage, such as text, images, links and more. HTML tells the computer what you want to see, the computer can read and interpret the HTML and produce an output.

WHERE IS HTML USED?

HTML is used to create websites. Every website in existance is written in HTML. In fact, this website that you are on right now was written in HTML. Whilst the primary use of HTML is websites, it is also sometimes used to create emails as well as mobile and desktop apps.

WHY LEARN HTML?

With HTML, you can make your own websites. You can build personal blogs, portfolios, or business websites, and have full control over the content and layout. HTML is also a highly sought-after skill in many job markets. With the rise of the internet, HTML is ever-so relevant to learn.

WHERE DO I WRITE HTML?

To write HTML, you need a text editor. A text editor is simply an application that allows you to write and edit text. When first starting out, it is best to use a simple text editor such as the text editors that already come preinstalled on all desktop computers:

On MacOS Open Finder > Applications > TextEdit
On WindowsOS Start > Search & Open "Notepad"
On ChromeOS Launcher > Search & Open "Text"

WRITING HTML

HTML is written in tags. Tags are basically the instructions that tell tht computer what to do. Tags are written with a less than sign (<) followed by the tag name and then a greater than sign (>). Then follows the content of the tag. After the content, the tag needs to be closed, to do this, we write a closing tag which is a repition of the opening tag with a forward slash (/) after the less than sign (<)

An example of how a tag is written:

<tag> content </tag>

Some tags don't have any content between them. When this is the case, we only write one tag, not two. However, when only writing one tag, this tag need to close itself, so we write the tag as normal but put a forward slash (/) before the greater than (<) sign

An example of how a self-closing tag is written:

<tag/>

Essential Tags

Before writing any tags we must always include two essential tags at the very top of our document. We must write <!DOCTYPE html> just once. The <!DOCTYPE html> tag declares that the file is a HTML file, which is important for the web browser to know when processing files

The essential tag that must always be present at the top of any HTML document

<!DOCTYPE html>

We must also always include the <html> tag when writing html. We embed all of the HTML inside the <html> tag.

The two essential tags of any HTML document

<!DOCTYPE html>
                      <html>

                      All Content

                      </html>

Text Tags

In order to write on a webpage, we must use text tags. Titles and subtitles are usually written using heading tags. Headings are written using the <h1> to <h6> tags. The <h1> tag is the biggest tag in terms of size, and the <h6> tag is the smallest.

HTML

<h1>Heading 1</h1>

Separating Parts of Webpages

Webpages need to separate paragraphs, images, etc. to make them easier for a user to read.

To separate elements, we can use the <br/> tag to create a line break. This adds a blank, vertical spacing between elements. The <br/> tag is a self-closing tag.

HTML

<!DOCTYPE html>
                      <html>
                      <p>Paragraph 1</p>
                      <br/>

                      </html>

Displayed

Paragraph 1

Paragraph 2

If we want to separate elements with a horizontal line, we can use the <hr/> tag.

HTML

<!DOCTYPE html>
                      <html>
                      <p>Paragraph 1</p>
                      <hr/>

Paragraph 2

Images

To add an image, we can use the <img> tag. Inside of the <img> tag we use the atributes src and alt. The src attribute is used to specify the source of the image. The alt attribute is used to specify an alternative text to describe the image which helps with seo and accessibility. The alt text will be displayed if the image can not be loaded. Inside of the image tag we must also set the width and height attributes. The width and height attributes are used to specify the width and height of the image. The height and width can be specified in pixels or in percent. The <img> tag does not need to be closed.

HTML

<img src="https://i.imgur.com/xCPZT2V.jpg" alt="The Arc De Triomphe Monument in Paris" width="50%" height="50%">

Audio

To add an audio file, we can use the <audio> tag. Inside of the <audio> tag we use the atributes src and controls. The src attribute is used to specify the source of the audio file. The controls attribute is used to specify whether the user can control the audio file (Play, Stop, Volume, Skip). The controls attribute can be set to true or false.

HTML

<audio src="xyzzzpoemchargeofthelightbrigade.mp3" controls></audio>

Displayed

Video

To add a video file, we can use the <video> tag. Inside of the <video> tag we use the atributes src and controls. The src attribute is used to specify the source of the video file. The controls attribute is used to specify whether the user can control the video file (Play, Stop, Volume, Skip). The controls attribute can be set to true or false.

HTML

<video src="https://i.imgur.com/dlEu1yM.mp4" controls></video>

Lists

Lists can be created in HTML using the <li> tag. The <li> tag is used to create a list item. Lists can be ordered or unordered. Unodered lists use bullet points. Ordered lists use numbers. Ordered lists need to be nested in a pair of <ol> tags and unordered lists need to be nested in a pair of <ul> tags.
Let's create an ordered list in HTML:

HTML

<ol>
                      <li>Pizza</li>
                      <li>Pasta</li>
                      <li>Ice Cream</li>
                      </ol>

Displayed

Pizza
Pasta
Ice Cream

And here is an unodered HTML list:

HTML

<ul>
                      <li>Pizza</li>
                      <li>Pasta</li>
                      <li>Ice Cream</li>
                      </ul>

Buttons

To create clickable buttons in HTML, we use the <button> tag.
Let's create a button that says "Click Me":

HTML

<button>Click Me</button>

Displayed

Hyperlinks

Hyperlinks are used to link to other parts of the website or other websites. To create a hyperlink, we use the <a> tag. Inside of the <a> we must include the atribute href. The href attribute is used to specify the destination of the link. The href attribute can be set to a URL or a file path. We can add a hyperlink to a text element, image or button.
Let's create a button with hyperlink to my photography website:

HTML

<a href="https://photography.samfield.org"><button>Click Me</button></a>

Displayed

Clicking that button will open that webpage in place of this one. We can open the webpage in a new tab by using the target attribute. By setting the target attribute to _blank, the webpage will open in a new tab.

HTML

<a href="https://photography.samfield.org" target="_blank"><button>Click Me</button></a>

WHAT IS CSS?

CSS stands for Cascading Style Sheet. A style sheet is a document that defines the presentation and formatting of a structured document. Style sheets specify how elements should be displayed on the screen. CSS is used to style a HTMl document. CSS allows us to change the colour, font, size, layout and so much more of a HTML document.

WHERE IS CSS USED?

CSS is used to style HTML documents therefore CSS is responsible for the design of a website.

WHY LEARN CSS?

With CSS, you can enhance your own websites. You can have full control over the content and layout. CSS is also a highly sought-after skill in many job markets. With the rise of the internet, CSS is ever-so relevant to learn..

WHERE DO I WRITE CSS?

To write CSS, you need a text editor. A text editor is simply an application that allows you to write and edit text. When first starting out, it is best to use a simple text editor such as the text editors that already come preinstalled on all desktop computers:

On MacOS Open Finder > Applications > TextEdit
On WindowsOS Start > Search & Open "Notepad"
On ChromeOS Launcher > Search & Open "Text"

WRITING CSS

CSS is used to style HTML documents. To insert CSS into a style sheet, we can use three different ways:

External CSS

Internal CSS

In-line CSS

External CSS

To insert CSS using the external method, we need to create a new file with the .css extension. We can then link to that file in our HTML document. We can then write all of our CSS in the .css file. The syntax for this is as follows:

HTML

<!DOCTYPE html>
 <html>
  <head>
   <link rel="stylesheet" href="style.css">
  </head>
 </html>

Displayed

Internal CSS

To insert CSS using the internal method, we can use the <style> tag. We can then write all of our CSS in the <style> tags. The syntax for this is as follows:

HTML

<!DOCTYPE html>
  <html>
    <style>

      CSS goes here

    </style>
  </html>

Displayed

In-line CSS

To insert CSS using the in-line method, we can use the style attribute inside of a HTML element. We can then write all of our CSS in the style attribute. The syntax for this is as follows:

HTML

<!DOCTYPE html>
                          <html>
                           <h style="CSS goes here"><h>
                          </html>

Displayed

Cascading Order

If multiple CSS rules are acting on one element, the element will only output the CSS of the rule of highest priority. The priority of CSS styles is as follows:

In-line Style
Internal Style
External Style

WHAT IS MathML?

MathML stands for Mathematical Markup Language. A markup language is a way to write down information with embedded instructions that tell a computer how to interpret and display that information. MathML is like a special language that computers use to write and show math problems, equations, expressions, shapes and more. MathML is the way the computer understands what we want to see, so it can show the math problems correctly on the screen.

WHERE IS MathML USED?

MathMl is most commonly used to display mathematical information on websites. MathMl is also used in mobile and desktop applications and E-books.

WHY LEARN MathML?

MathML allows you to represent mathematical formulas and equations accurately on web pages and digital documents. This is especially useful for webdevelopers, educators, researchers, and anyone involved in publishing mathematical content online. As more educational and professional content moves online, the ability to create and manage mathematical content using MathML will become increasingly important.

WHERE DO I WRITE MathML?

To write MathML, you need a text editor. A text editor is simply an application that allows you to write and edit text. When first starting out, it is best to use a simple text editor such as the text editors that already come preinstalled on all desktop computers:

On MacOS Open Finder > Applications > TextEdit
On WindowsOS Start > Search & Open "Notepad"
On ChromeOS Launcher > Search & Open "Text"

Writing MathML

Essential Tags

Before writing any tags we must always include the essential <math> tag to encapsulate all of our MathMl inside of. The <math> tag can be put inside of a HTML Document.

HTML

<!DOCTYPE html>
  <html>
   <math>

      All MathML content

   </math>
  </html>

Displayed

All MathMl content

Writing Values

When writing values (numbers, algebraic letters, pi, sin, cos, tan, ect.) we use the <mi> tag. The <mi> tag stands for Mathamatical Identifiers.
Lets write 476 in MathML.

MathML

<math>
    <mi>476</mi>
</math>

Displayed

476

Writing Operators

When writing operators (times, divide, plus, minus, ect.) we use the <mo> tag. The <mo> tag stands for Mathamatical Operators. Each operator has its own unique hex code to represent it:


                        - Minus &#x2212;

                        + Plus &#x2B;

                        × Multiply &#x00d7;

                        ÷ Divide &#x00f7;

                        = Equal &#x003D;

                        ≠ Not Equal &#x2260;

                        ≈ Approximately Equal &#x2248;

                        < Less Than &#x003c;

                        ≤ Less Than or Equal &#x2264;

                        > Greater Than &#x003e;

                        ≥ Greater Than or Equal &#x2265;

                        ± Plus or Minus &#x00b1;

                        ∝ Proportional &#x221d;

                        ∑ Summation &#x2211;

                        ∏ Product &#x220f;

                        ⌊ Left Floor Parenthesis &#x230a;

                        ⌋ Right Floor Parenthesis &#x230b;

                        ⌈ Left Ceiling Parenthesis &#x2308;

                        ⌉ Right Ceiling Parenthesis &#x2309;

So, if we want to write a multiplication sign, we would write:

MathML

<math>
     <mo>&#x00d7;</mo>
</math>

Displayed

\times

Writing Simple Equations

So now that we know how to write values and operators, we can start writing equations. To write an equation, we must put our value and operator tags indside an <mrow> tag. The <mrow> tag stands for Mathamatical Row.
Let's write 4 + 3 = 7 in MathML.

MathML

<math>
 <mrow>   

 <mi>4/<mi><mo>&#x2B;</mo><mi>3</mi><mo>&#x003D;</mo><mi>7</mi>
 </mrow>
</math>

Displayed

4 + 3 = 7

Writing Fractions

To write fractions, we must use the <mfrac> tag. Inside the <mfrac> tag, we must write the numerator and denominator tags, these are both written using the <mn> tag.
Let's write 0.5 in MathML.

MathML

<math>
    <mrow>   
        <mfrac><mn>1</mn><mn>2</mn></mfrac>
    </mrow>
</math>

Displayed

\frac{1}{2}

How To Write Indices

To write indices, we use the <msup> tag around the entire number and the <mn> tag around just the power.

Let's write 2³ in MathML.

MathML

<math>
   <mrow>  
       <msup><mi>2</mi><mn>3</mn></msup>
   </mrow>
</math>

Displayed

2^{3}

Writing Roots in MathML

To write roots in MathML, we use the <root> tag. The <root> surrounds the <mi> tag (The number being rooted) and <mn> tag (The root number).
Let's write the cube root of 69 in MathML.

MathML

<math>
   <mrow>  
       <mroot><mi>69</mi><mn>3</mn></mroot>
   </mrow>
</math>

Displayed

\sqrt[3]{69}

Writing The Quadratic Formula in MathML

We now have all of the neccessary MathML knowledge to put together and write a more complex equation such as the quadratic fromula.
Let's write the quadratic formula in MathML:

MathML

<math>
  <mrow>
<mi>x</mi><mo>&#x003D;</mo><mfrac><mrow><mrow><mo>&#x2212;</mo><mi>b</mi></mrow><mo>&#x00b1;</mo><mroot><mrow><msup><mi>b</mi><mn>2</mn></msup><mo>&#x2212;</mo><mrow><mn>4</mn><mo>&#x2062;</mo><mi>a</mi><mo>&#x2062;</mo><mi>c</mi></mrow></mrow><mn>2</mn></mroot></mrow><mrow><mn>2</mn><mo>&#x2062;</mo><mi>a</mi></mrow></mfrac>

WHAT IS PYTHON?

Python is a general purpose programming language. We use python to give instructions to computers.

WHERE IS PYTHON USED?

Python is used in web development, software development, mathematics, system scripting and more.

WHY LEARN PYTHON?

Python is great for beginners as it has an easy to read syntax. It is also a very popular language and is used in many fields. Python can even be embedded into HTML documents, making it a great choice for those interested in web development.

WHERE DO I WRITE PYTHON?

To write Python, you can either use a web based IDE (such as Replit.com open_in_new) or you can use a local text editor. A text editor is simply an application that allows you to write and edit text. When first starting out, it is best to use a simple text editor such as the text editors that already come preinstalled on all desktop computers:

On MacOS Open Finder > Applications > TextEdit
On WindowsOS Start > Search & Open "Notepad"
On ChromeOS Launcher > Search & Open "Text"

NOTE: IF USING A LOCAL TEXT EDITOR YOU MAY NEED TO INSTALL PYTHON FROM python.orgopen_in_new

Writing Python

Embedding Python into HTML

To embed Python into HTML, we first must add a script defer: <script defer src="https://pyscript.net/alpha/pyscript.js"></script> inside of our HTML <head> tags. We can then use the <py-script> tag. We must write all of our python inside of the <py-script> tags.

HTML

<!DOCTYPE html>
 <html>

Printing Things

To print things onto a screen in python, we use the code: print("").
Let's print "Hello World!" in python:

python

print("Hello World!")

Displayed

print("Hello World!")

Variables

A variable is a name that stores a value. Variables are useful because instead of remembering everything, we can just remember the name of the variable. We can assign a value to a variable using the code: variable_name = value.

Let's create a variable called "name" and assign it the value "John".

python

name = "John"


print(name)

Displayed

name = "John" print(name)

NOTE: YOU MUST HAVE AT LEAST A TWO LINE GAP BETWEEN THE VARIABLE AND PRINT

Now let's create multiple variables and print them in different ways

python

name = "John"
surname = " Doe"
age = 69
wife = "Jane"
wife_surname = " Doe"
wife_age = 6900


 print(name+surname)

Displayed

name = "John" surname = " Doe" age = 69 wife = "Jane" wife_surname = " Doe" wife_age = 6900 print(name+surname)

python

Comparing Values

We can compare values using python. We write two equals signs (==) to compare values. We can also compare values using greater than (>) or less than (<) signs as well as greater than or equal to (>=) or less than or equal to signs (<=). An exclamation mark means that the opposite is true (the value is not equal to the other value). The output will either be true or false, this is useful for creating things like passcodes and verification codes.

python

5 == 5

Displayed

5 == 5

python

9 == 5

Displayed

9 == 5

python

9 > 5

Displayed

9 > 5

python

9 != 5

Displayed

9 != 5

Conditional (If/Else) Statements

We can write conditional statements to output different things depending on the value of a variable. We use the if statement to check if a value is true or false.

python

if name == "John":
print("Hello John")
else:
print("I don't know you")

Displayed

if name == "John": print("Hello John") else: print("I don't know you")

Now let's see what happens when the opposite is true.

python

if name != "John":
print("Hello John")
else:
print("I don't know you")

print("Hello, John") 
} else if (name == "Jane") {
print("Hello, Jane")

We can nest ifs inside of other ifs which allows you to test multiple criteria and increases the number of possible outcomes

score <- "69"

if (score > 30) {
print("Your score is above 30")
if (score > 50) {
print("and also above 50!")
} else {
print("but not above 50.")
}
} else {
print("Your score is below 30.")
}
