CSS Syntax

The syntax of CSS consists of three parts: selector, property, and value. Here is an example:

selector {
  property: value;
}

• Selector: Selects the HTML element that you want to style. It could be a tag name, class, ID, or other selectors.
• Property: Specifies the property of the selected element that you want to change, such as color, font-size, padding, margin, etc.
• Value: Sets the value of the property that you want to apply to the selected element.

For example, the following CSS code sets the text color of all <p> elements to red:

p {
  color: red;
}

Here, p is the selector, color is the property, and red is the value.

CSS also supports multiple selectors and properties in a single rule. For example:

h1, h2, h3 {
  font-family: Arial, sans-serif;
  color: #333;
}

Here, the rule sets the font family and color for all <h1>, <h2>, and <h3> elements.

CSS also allows you to group multiple rules together. For example:

h1 {
  font-family: Arial, sans-serif;
  color: #333;
}

p {
  font-family: Georgia, serif;
  font-size: 16px;
  line-height: 1.5;
}

Here, two rules are grouped together to set the font family and color for all <h1> elements, and the font family, size, and line height for all <p> elements.

In addition, CSS allows you to add comments to your code using /* */ notation. For example:

/* This is a comment */
h1 {
  font-family: Arial, sans-serif;
  color: #333; /* This is also a comment */
}

Comments are ignored by the browser and are used to provide notes or explanations to your code.
