CSS syntax is relatively straightforward and consists of a set of rules defining how to apply styles to HTML elements. Each rule is composed of a selector, followed by a set of curly braces that contain one or more property-value pairs. The general structure of a CSS rule is as follows:
```
selector {
property1: value1;
property2: value2;
/* Additional properties and values */
}
```
Here's a breakdown of the components:
1. Selector: The selector is used to target HTML elements to which the styles will be applied. It can be a tag name (e.g., `p`, `h1`, `div`), a class name (e.g., `.my-class`), an ID (e.g., `#my-id`), or other more complex selectors.
2. Property: The property represents the aspect of the element that you want to style, such as `color`, `font-size`, `margin`, `padding`, etc.
3. Value: The value is the specific setting you want to apply to the selected property. For example, `red` for color, `16px` for font-size, `10px 20px` for margin, etc.
Multiple properties and values can be included within the curly braces, separated by semicolons. CSS allows you to apply styles globally or target specific elements based on their classes, IDs, or hierarchical relationships.
Here's an example of a simple CSS rule that changes the color and font-size of all paragraphs:
```
p {
color: blue;
font-size: 16px;
}
```
This rule targets all `<p>` elements and sets their text color to blue and font size to 16 pixels.
