CSS stands for Cascading Style Sheets. It is a language used to style web pages. CSS is used to control the look and feel of a web page, such as the font, color, and layout of the text, as well as the size and position of images and other elements.
CSS is a separate language from HTML, which is used to structure the content of a web page. However, CSS and HTML work together to create the final look of a web page.
CSS Basics
The basic unit of CSS is a rule. A rule consists of a selector and a declaration. The selector is used to select the element that the rule will apply to. The declaration specifies the property and value that will be applied to the selected element.
For example, the following rule would set the font size of all <h1> elements to 24px:
CSS
h1 {
font-size: 24px;
}
