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;
}
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;
}
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;
}
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;
}
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;
}
6. Child Selector - Target Direct Children:
Child selectors target elements that are direct children of a parent element.
ul > li {
list-style-type: square;
}
7. Adjacent Sibling Selector - Style Immediately Following Elements:
This selector targets an element that directly follows another element.
h2 + p {
font-style: italic;
}
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;
}
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;
}
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;
}
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;
}
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;
}
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;
}
