Basic HTML Elements
Here are some commonly used HTML elements:
<html>: The root element of an HTML page.<head>: Contains meta information about the HTML page, like the title and links to stylesheets.<title>: Specifies a title for the HTML page.<body>: Contains the visible content of the HTML page.<h1>to<h6>: Heading tags, with<h1>being the most important.<p>: Defines a paragraph.<a>: Defines a hyperlink.<img>: Embeds an image.<ul>: Defines an unordered list.<li>: Defines a list item.
Introduction to CSS
CSS, or Cascading Style Sheets, is used to style HTML elements. It controls the presentation of a website, including colors, fonts, layout, and more. CSS allows you to separate the style from the structure, making websites easier to maintain and update.
Basic CSS Concepts
Some fundamental CSS concepts include:
- Selectors: Used to target HTML elements that you want to style.
- Properties: The attributes you want to style (e.g., color, font-size, margin).
- Values: The specific settings for the properties (e.g., red, 16px, 10px).
CSS is applied to HTML in various ways such as:
- Inline CSS: Applied directly within HTML elements using the style attribute.
- Internal CSS: Defined in the
<style>element within the<head>section. - External CSS: Written in a separate CSS file and linked to HTML using the
<link>element.
CSS Box Model
The CSS Box Model is a concept that every HTML element consists of a box. Understanding the box model is crucial to controlling layout with CSS. It comprises the following:
- Content: The actual content of the element.
- Padding: Clears an area around the content.
- Border: Goes around the padding and content.
- Margin: Clears an area outside the border.
Getting Started
To start with HTML & CSS, all you need is a text editor and a web browser. Create an HTML file and start experimenting with basic elements. Then, add a CSS file and learn how selectors, properties, and values work. This is the foundation of web development. Start coding and exploring the possibilities!
