What does @ in css mean?

In CSS, the "@" symbol indicates the beginning of a directive or rule set. Directives provide CSS interpretation information, rule sets contain rules for styling HTML elements, and the "@" symbol in an attribute value represents a variable or function.

The meaning of the @ symbol in CSS

In CSS, the "@" symbol is a special character. Used for the following purposes:

1. Directives

@ The "@" symbol indicates a CSS directive that provides information on how to interpret other CSS rules. The most common instructions are:

• @charset: Specifies the character encoding of the text file.
• @import: Import another CSS file.
• @media: Applies different styles based on device or media type.

2. Rulesets

@The "@" symbol can also be used to create a rule set, which contains a set of rules for HTML elements are styled. The ruleset syntax is as follows:

<code>@selector {
  property: value;
}</code>

For example:

<code>@p {
  font-size: 12px;
}</code>

This will set a font size of 12 pixels for the <p></p> element in HTML.

3. Attribute value

In CSS attribute values, the @"@" symbol is sometimes used to indicate a variable or function. For example:

<code>color: @primary-color;</code>

This sets the color property to the value of a variable named @primary-color.

Note:

• The "@" symbol in CSS is critical for correct interpretation of style sheets.
• It must be placed at the beginning of each directive or rule set line.
• If "@" is used incorrectly, the CSS parser will not understand the code and may cause styling errors.
