🎯 CSS Selectors: Targeting Elements with Precision

CSS Selectors are the heart of styling in CSS. They let you “select” the HTML elements you want to style—whether it’s a single element, a group, or elements with specific attributes. Think of them as smart pointers that guide your styles exactly where they need to go.

🔍 What is a CSS Selector?

A selector defines the HTML element(s) to which a set of CSS rules should be applied. Without selectors, CSS would have no idea what to style!

📚 Common Types of CSS Selectors (with Examples)

1. Universal Selector (*)

Selects all elements on the page.

cssCopyEdit* {
  margin: 0;
  padding: 0;
}

2. Element Selector

Targets all elements of a specific type.

cssCopyEditp {
  color: #333;
  font-size: 16px;
}

3. Class Selector (.className)

Targets elements with a specific class.

htmlCopyEdit<div class="box">Hello!</div>

cssCopyEdit.box {
  background-color: #f5f5f5;
  padding: 20px;
}

4. ID Selector (#idName)

Targets a single, unique element by its ID.

htmlCopyEdit<h1 id="main-heading">Welcome to GoNimbus</h1>

cssCopyEdit#main-heading {
  color: #2c3e50;
}

5. Group Selector

Style multiple elements with the same rules.

cssCopyEdith1, h2, h3 {
  font-family: 'Poppins', sans-serif;
}

6. Descendant Selector

Selects elements inside another element.

cssCopyEditarticle p {
  line-height: 1.6;
}

7. Child Selector (>)

Targets only direct children.

cssCopyEditul > li {
  list-style-type: square;
}

8. Attribute Selector

Targets elements based on attribute values.

cssCopyEditinput[type="text"] {
  border: 1px solid #ccc;
}

9. Pseudo-class Selector

Targets elements based on their state or position.

cssCopyEdita:hover {
  color: #ff6600;
}

cssCopyEditli:first-child {
  font-weight: bold;
}
