- The Adjacent Sibling Selector is a selector in CSS that allows you to target an element that immediately follows another specific element. It is denoted by the plus sign (+) and is used to select the sibling element that comes immediately after the specified element.
The general syntax of the Adjacent Sibling Selector is as follows:
element1+element2 {
/* CSS properties */
}
- Here, `element1` is the reference element, and `element2` is the target element that immediately follows `element1`. The CSS properties defined within the curly braces will be applied to `element2`. Let's consider an example to understand the Adjacent Sibling Selector better.
- let's say you want to apply a specific style to the paragraph <p> tag, only if it directly follows the <h1> tag. You can achieve this using the Adjacent Sibling Selector in CSS. Suppose you have the following HTML structure:
<!DOCTYPE html>
<html lang="en">
<head>
<style>
h1+p {
color: blue;
}
</style>
<title>Document</title>
</head>
<body>
<div class="parent">
<h1>Title</h1>
<p>Some text</p>
<p>paragraph 2</p>
<div class="child">
<h1>new heading</h1>
<p>hello world</p>
<p>
paragraph 1
</p>
</div>
</div>
</body>
</html>
- In this example, the CSS code selects the `<p>` element that directly follows the `<h1>` element and applies the color property to make the text blue.
- It's important to note that the Adjacent Sibling Selector only selects the immediate sibling element. If there are other elements between `element1` and `element2`, the selector won't match.
<!DOCTYPE html>
<html lang="en">
<head>
<style>
.parent #child + h1 {
color: red;
}
</style>
<title>Document</title>
</head>
<body>
<div class="parent">
<h1>Title</h1>
<p>Some text</p>
<p>paragraph 2</p>
<div id="child">
<p>hello world</p>
<p>
paragraph 1
</p>
</div>
<h1>new heading</h1>
</div>
</body>
</html>
- In summary, the Adjacent Sibling Selector in CSS allows you to select and apply styles to an element that immediately follows another specific element. It is denoted by the plus sign (+) and can be useful for styling specific elements based on their position within the HTML structure.
