Study Notes

Structuring Web Content with HTML

HTML (Hypertext Markup Language) is the foundation for structuring content on the web. It assigns semantic meaning to elements, such as headings, lists, and tables, to help browsers display the content in a meaningful way.

HTML Elements and Content Categories

HTML elements are grouped into three major categories:

Flow content: Contains content that flows around floats and is not affected by them. Examples include <p>, <h1>, and <div>.
Sectioning content: Defines sections of documents. Examples include <header>, <nav>, and <article>.

HTML Structural Tags

To mark up content, use the following structural tags:

<article>: Represents an independent piece of content.
<header>: Contains a heading or a group of introductory or navigational aids.
<nav>: Represents a section that links to other pages or sections within the same document or website.
<section>: Represents a generic document or application section.

Writing Good HTML

When writing HTML, keep these tips in mind:

Use descriptive and semantic tags.
Use HTML5 tags, rather than deprecated tags.
Avoid overreliance on CSS to hide poor HTML structure.
Validate your HTML using online validators, such as the W3C Validator.

Styling Web Content with CSS

CSS (Cascading Style Sheets) is a language used to style HTML documents and control their layout. It specifies how HTML elements should be displayed, including fonts, colors, and positions.

CSS Selector Types

CSS selectors categorize HTML elements and allow you to apply styles to them. Common selector types include:

Element selectors (e.g., h1)
Class selectors (e.g., .my-class)
ID selectors (e.g., #my-element)

Writing Good CSS

Separate CSS into external files when possible.
Use CSS selectors to target HTML elements correctly.
Avoid using inline CSS styles, except when needed for specific situations.
Validate your CSS using online validators, such as the W3C CSS Validator.

CSS Properties

To style HTML elements, use the following CSS properties:

color: Sets the text color.
font-family: Defines the font.
font-size: Sets the font size.
border: Adds borders.
padding: Adds padding inside borders.
margin: Adds margin outside borders.

CSS Layout Concepts

Flexbox: A powerful layout system that allows for responsive and fluid layouts.
Grid: A grid-based layout system that helps create complex and responsive layouts.

By structuring content with HTML and styling it with CSS, you can create modern, accessible, and visually appealing web pages. Always strive to write clean and valid HTML and CSS, and keep learning to stay up to date with the latest web technologies.
