HTML Basics:

Tags: HTML uses tags. Most come in pairs. <p> starts a paragraph, and </p> ends it.
Elements: An HTML element has a start tag, content, and an end tag. Simple!
Attributes: These give more info about elements. Like <img src="image.jpg" alt="My Image">. The src tells the image source.
The Structure: Every HTML page has a structure:
- <!DOCTYPE html>: Tells the browser what kind of document this is.
- <html>: The main part of the page.
- <head>: Info about the page. Like the title and links to CSS.
- <body>: The stuff you see on the page.

Important HTML Tags:

Here are some HTML tags you'll use a lot:

<h1> to <h6>: Different sized headings.
<p>: A paragraph.
<a>: A link.
<img>: An image.
<ul>: A list (unordered).
<ol>: A list (ordered).
<li>: A list item.
<div>: A section.
<span>: A small piece of text.
<table>, <tr>, <td>: For making tables.
<form>, <input>, <button>: For making forms.

What is CSS?

CSS makes your website look good. It controls the colors, fonts, and layout. It's like makeup for your web page.

CSS Basics:

Selectors: Pick the HTML elements you want to style. You can pick elements, classes, or IDs.
Properties: These are the styles you apply. Like color or font-size.
Values: What value to give a property? color: blue; makes the text blue.
Rulesets: A selector and the styles you give it. Like this:
```
  selector {
   property: value;
  }
  
```

How to Use CSS in HTML:

Inline Styles: Put the style right in the HTML tag. (Not a good idea for big projects).
Internal Styles: Use a <style> tag in the <head>.
External Stylesheets: Save your CSS in a .css file. Link it to your HTML. (This is the best way!)

Important CSS Properties:

Here are some CSS properties you'll use a lot:

color: The text color.
font-size: How big the text is.
font-family: What font to use.
background-color: The background color.
margin: Space around the element.
padding: Space inside the element.
border: A border around the element.
width: How wide the element is.
height: How tall the element is.
