HTML and CSS
CSS stands for Cascading Style Sheets. CSS saves a lot of work. It can control the layout of multiple web pages all at once.
What is CSS?
Cascading Style Sheets (CSS) is used to format the layout of a webpage. With CSS, you can control the color, font, the size of text, the spacing between elements, how elements are positioned and laid out, what background images or background colors are to be used, different displays for different devices and screen sizes, and much more!
Using CSS
CSS can be added to HTML documents in 3 ways:
- Inline - by using the
styleattribute inside HTML elements - Internal - by using a
<style>element in the<head>section - External - by using a
<link>element to link to an external CSS file
The most common way to add CSS, is to keep the styles in external CSS files. However, in this tutorial we will use inline and internal styles, because this is easier to demonstrate.
Inline CSS
An inline CSS is used to apply a unique style to a single HTML element. An inline CSS uses the `style` attribute of an HTML element.
Internal CSS
An internal CSS is used to define a style for a single HTML page. An internal CSS is defined in the `<head>` section of an HTML page, within a `<style>` element.
External CSS
An external style sheet is used to define the style for many HTML pages. With an external style sheet, you can change the look of an entire web site, by changing one file! To use an external style sheet, add a link to it in the `<head>` section of the HTML page.
