2025-03-01 23:23:04What is HTML?
HTML (HyperText Markup Language) is the foundation of all webpages. Think of it as the framing of a house - it provides the basic structure that everything else builds upon.
Key Concepts
- HTML is a markup language, not a programming language
- It tells browsers how to structure web content
- Every HTML element is like a building block
- Browsers interpret HTML to display content
The Building Analogy
When building a webpage, think of it like constructing a house: - HTML: The framing and structure (walls, rooms, layout) - CSS: The design elements (paint, decorations, styling) - JavaScript: The functionality (plumbing, electrical, moving parts)
Basic HTML Structure
1. HTML Boilerplate
Every webpage starts with a basic template:
```html
Your Page Title ```
2. Understanding the Parts
<!DOCTYPE html>: Tells browsers this is an HTML5 document<html>: The root element of the page<head>: Contains metadata about the document<body>: Contains the visible content
Essential HTML Elements
1. Headings
HTML has six levels of headings: ```html
Main Title
Subtitle
Section Header
Smallest Heading
```
2. Paragraphs
```html
This is a paragraph of text. It can contain as much text as you need.
```
3. Images
html <img src="path-to-image.jpg" alt="Description of image" width="300">4. Links
html <a href="https://example.com">Click here</a>HTML Attributes
Attributes provide additional information or modify HTML elements:
html <tag attribute="value">Content</tag>Common attributes: -
src: Source path for images -href: Destination for links -alt: Alternative text for images -class: CSS class names -id: Unique identifier -style: Inline CSS stylesSemantic HTML
What is Semantic HTML?
Semantic HTML uses meaningful tags that describe their content's purpose. This improves: - Accessibility - SEO (Search Engine Optimization) - Code readability - Maintainability
Common Semantic Elements
```html
```
Non-Semantic vs Semantic Example
Instead of: ```html
```
Use: ```html
```
Building Your First Webpage
1. Basic Structure
```html
My First Webpage Welcome to My First Webpage!
About Me
Hi, I'm learning web development with PlebDevs!
My Interests
I'm interested in Bitcoin, programming, and building cool stuff!
```
Best Practices
1. Structure
- Use proper indentation
- Keep code organized and readable
- Use semantic elements when possible
- Include all required elements (
DOCTYPE,html,head,body)
2. Content
- Use appropriate heading levels (start with
h1) - Write descriptive
alttext for images - Keep content meaningful and organized
- Use comments to explain complex sections
3. Accessibility
- Use semantic HTML elements
- Provide alternative text for images
- Maintain a logical heading structure
- Ensure content makes sense when read linearly
Common Issues and Solutions
Problem: Images Not Loading
```html
```Problem: Links Not Working
```html

Next Steps
- Practice Building
- Create a personal webpage about yourself
- Include different types of content (text, images, links)
-
Use semantic HTML elements
-
Experiment with Structure
- Try different layouts
- Use various HTML elements
-
Pay attention to semantic meaning
-
Prepare for CSS
- Think about how you want your page to look
- Consider what styles you'll want to add
- Plan your layout structure
Exercise: Create Your Profile Page
Try creating a simple profile page using what you've learned:
- Use the HTML boilerplate
- Add a header with your name
- Include an "About Me" section
- Add a photo (if you want)
- List your interests or goals
- Add a footer with contact information
Remember to: - Use semantic HTML - Include appropriate headings - Add descriptive alt text for images - Keep your code clean and well-organized
