Introduction:

CSS (Cascading Style Sheets) is a a stylesheet language ⚙️ that allows web developers🧑🏻‍💻 to control the appearance of their websites. One of the fundamental concepts in CSS is 📌selectors, which determine which HTML elements🌐 to style. In this blog post💬, we'll take a deep dive into the different types of CSS selectors along with 👩🏻‍💻code examples to help you better understand how to apply⌨️ styles to specific elements on your web pages💻.

1. Universal Selector (*) - Select All Elements:

The universal selector, denoted by "*", selects all elements on a webpage. While it might seem like a broad approach, it can be useful for applying global styles.

 * { margin: 0; padding: 0; }
Enter fullscreen mode Exit fullscreen mode

2. Type Selector - Target Elements by Tag Name:

Type selectors target specific HTML elements based on their tag names. For example, you can style all <h1> elements in a consistent way.

 h1 { font-family: 'Arial', sans-serif; font-size: 24px; }
Enter fullscreen mode Exit fullscreen mode

3. Class Selector - Style Elements with Specific Classes:

Class selectors are preceded by a dot (.) and are used to style elements with specific class attributes.

 .button { background-color: #007bff; color: white; padding: 10px 20px; }
Enter fullscreen mode Exit fullscreen mode

4. ID Selector - Target Unique Elements:

ID selectors are preceded by a hash (#) and target elements with unique IDs.

 #header { background-color: #333; color: white; }
Enter fullscreen mode Exit fullscreen mode

5. Descendant Selector - Style Nested Elements:

Descendant selectors are used to style elements that are descendants of other elements.

 article p { line-height: 1.5; }
Enter fullscreen mode Exit fullscreen mode

6. Child Selector - Target Direct Children:

Child selectors target elements that are direct children of a parent element.

 ul > li { list-style-type: square; }
Enter fullscreen mode Exit fullscreen mode

7. Adjacent Sibling Selector - Style Immediately Following Elements:

This selector targets an element that directly follows another element.

 h2 + p { font-style: italic; }
Enter fullscreen mode Exit fullscreen mode

8. General Sibling Selector - Target Sibling Elements:

The general sibling selector selects elements that share the same parent and are at the same level in the hierarchy.

 h2 ~ p { color: #888; }
Enter fullscreen mode Exit fullscreen mode

9. Attribute Selector - Style Elements with Specific Attributes:

Attribute selectors allow you to target elements based on specific attribute values.

 input[type="text"] { border: 1px solid #ccc; }
Enter fullscreen mode Exit fullscreen mode

10. Pseudo-Class Selector - Style Elements Based on States:

Pseudo-classes target elements based on their states or interactions.

 a:hover { color: #ff9900; text-decoration: underline; }
Enter fullscreen mode Exit fullscreen mode

11. Pseudo-Element Selector - Style Specific Parts of Elements:

Pseudo-elements target specific parts of elements, such as adding content before or after an element's content.

 p::before { content: ">>"; font-weight: bold; }
Enter fullscreen mode Exit fullscreen mode

12. Grouping Selector - Apply Styles to Multiple Elements:

Grouping selectors allow you to apply the same styles to multiple selectors.

 h1, h2, h3 { font-family: 'Georgia', serif; }
Enter fullscreen mode Exit fullscreen mode

13. Not Selector (:not(selector)) - Exclude Specific Elements:

The :not() pseudo-class excludes elements that match a certain selector.

 p:not(.special) { opacity: 0.8; }
Enter fullscreen mode Exit fullscreen mode
