CSS Get the first div under the element
Get the first div under an element with CSS
In web development, CSS is often used to control the styles of elements on the page. Sometimes we need to select the first div under a certain element to set its style, which is a very common requirement in real-world development.
The following details how to use CSS to retrieve the first div under a certain element, along with some example code.
Method 1: Using the Child Selector
The child selector selects the child elements of an element. By using the child selector, we can select the first div under a particular element.
/* Select the first div under the parent element */
.parent > div:first-child {
/* Set styles */
}
In the above code, the > notation selects the first div under the parent element and then sets the style.
Here is a sample code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>CSS Select First Div Child</title>
<style>
.parent > div:first-child {
background-color: lightblue;
color: white;
padding: 10px;
}
</style>
</head>
<body>
<div class="parent">
<div>First div</div> <div>Second div</div>
<div>Third div</div>
</div>
</body>
</html>
In the example above, we select the first div under the parent element and set its background and text colors.
Method 2: Using Pseudo-Class Selectors
In addition to the child selector, we can also use the pseudo-class selector :first-child to select the first child element.
/* Select the first div */
.parent div:first-child {
/* Set style */
}
In this method, we directly select all child divs under the parent element and select the first one to set the style.
Here is a sample code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>CSS Select First Div Child</title>
<style>
.parent div:first-child {
background-color: lightblue;
color: white;
padding: 10px;
}
</style>
</head>
<body>
<div class="parent"> <div>first div</div>
<div>second div</div>
<div>third div</div>
</div>
</body>
</html>
In the above example, we use the :first-child selector to select the first div and set its style.
Summary
CSS provides multiple methods for accessing the first div within an element. We’ve introduced two methods, using child selectors and pseudo-class selectors, and provided corresponding code examples. In actual development, choose the appropriate method to implement styling based on your specific situation.
