What is a CSS file? CSS (Cascading Style Sheets) is a style description language used to design web pages
What is a CSS file? CSS files contain a set of rules that tell the browser how a web page should be displayed. The main task of CSS is to separate the description of the content of the web page from its display on the screen.
A CSS file consists of a set of rules, each of which includes a selector and a block of properties. The selector indicates which element on the page should be styled, and the properties block contains a description of the display parameters of this element. Example:
h1 {
font-size: 24px;
color: #333;
}In this example, the h1 selector points to the first-level heading, and the properties block contains two parameters: font-size and color, which specify the font size and color of the heading text.
CSS files can be included in an HTML page using a tag. Example:
<head>
<link rel="stylesheet" href="styles.css">
</head>This tag indicates that the page uses an external CSS file styles.css.
CSS can also be embedded directly into an HTML document using a tag
<head> <style> h1 { font-size: 24px; color: #333; } </style> </head>In this example, CSS styles are embedded directly into the HTML document.
CSS is a powerful tool for designing web pages. With its help, you can change the sizes, colors, fonts, location and many other parameters of the elements on the page. Using CSS, you can make the page more attractive and functional for users.
