Unlocking the Power of HTML and CSS: A Comprehensive Guide

Key Highlights of HTML and CSS

HTML (HyperText Markup Language) is the backbone of web content, providing structure and meaning to elements on a webpage.
CSS (Cascading Style Sheets) dictates the visual presentation of HTML elements, controlling layout, colors, fonts, and more.
Learning HTML and CSS is the first step for anyone aspiring to become a web developer, opening doors to creating interactive and visually appealing websites.

What are HTML and CSS?

HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are the foundational technologies for building websites. HTML provides the structure and content of a webpage, while CSS controls its visual presentation. Together, they enable developers to create engaging and accessible web experiences.

HTML: Structuring Web Content

HTML uses a system of elements and tags to define the structure of a webpage. These elements can represent headings, paragraphs, links, images, lists, and more.

Here's a basic example of HTML code:


    <!DOCTYPE html>
    <html>
    <head>
      <title>My First Webpage</title>
    </head>
    <body>
      <h1>Hello, World!</h1>
      <p>This is a paragraph of text.</p>
    </body>
    </html>

In this example:

<!DOCTYPE html> declares the document as HTML5.
<html> is the root element of the page.
<head> contains meta-information about the HTML document, such as the title.
<title> specifies a title for the HTML page (which is shown in the browser's title bar or tab).
<body> contains the visible page content.
<h1> defines a large heading.
<p> defines a paragraph.

CSS: Styling Web Content

CSS is used to control the presentation of HTML elements, including their layout, colors, fonts, and other visual aspects. CSS rules are typically defined in separate CSS files or embedded within the HTML document using the <style> tag.

Here's an example of CSS code:


    h1 {
      color: #cc9900;
      text-align: center;
    }

    p {
      font-size: 16px;
      line-height: 1.5;
    }

In this example:

The h1 rule sets the color of all <h1> elements to #cc9900 (orange) and aligns the text to the center.
The p rule sets the font size of all <p> elements to 16 pixels and the line height to 1.5.

`<table>`	The container for all table elements.	`<table>...</table>`
`<tr>`	Defines a table row.	`<tr>...</tr>`
`<th>`	Defines a table header cell.	`<th>...</th>`
