How to use CSS to make a div fixed at the bottom right corner of its parent div
In web page layouts, it’s sometimes necessary to pin a Div element to the bottom right corner of its parent Div. This layout is often used to display fixed content, such as a back-to-top button or online customer service. This article will introduce several methods for achieving this layout, including absolute positioning, flex layout, and grid layout.
Method 1: Using Absolute Positioning
Absolute positioning is a common layout method that allows elements to be positioned outside the document flow, relative to their parent element. Here’s a simple example code demonstrating how to use absolute positioning to pin a div to the bottom right corner of its parent div:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Div fixed to the bottom right corner</title>
<style>
.parent {
position: relative;
width: 300px;
height: 200px;
border: 1px solid #ccc;
}
.child {
position: absolute;
bottom: 0;
right: 0;
width: 100px;
height: 50px;
background-color: #f00;
}
</style>
</head>
<body>
<div class="parent">
<div class="child"></div>
</div>
</body>
</html>
In the example above, we set the position: relative;, and then set the child div to position: absolute; bottom: 0; right: 0;. This will anchor the child div to the bottom right corner of the parent div.
Method 2: Using Flex Layout
Flex layout is a flexible layout method that can easily achieve a variety of complex layout effects. Here’s an example using flex layout to pin a div to the lower right corner:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Div Pinned to the Lower Right Corner</title>
<style>
.parent {
display: flex;
justify-content: flex-end;
align-items: flex-end;
width: 300px;
height: 200px;
border: 1px solid #ccc;
}
.child {
width: 100px;
height: 50px;
background-color: #0f0;
}
</style>
</head>
<body>
<div class="parent">
<div class="child"></div>
</div>
</body>
</html>
In the above example, we set display: flex; justify-content: flex-end; align-items: flex-end; on the parent div, which will cause the child div to be fixed to the lower right corner of the parent div.
Method 3: Using Grid Layout
Grid layout is a two-dimensional layout method that can easily achieve various complex grid layout effects. Here’s an example code that uses a grid layout to pin a div to the lower right corner:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Div Pinned to the Lower Right Corner</title>
<style>
.parent {
display: grid;
place-items: end end;
width: 300px;
height: 200px;
border: 1px solid #ccc;
}
.child {
width: 100px;
height: 50px;
background-color: #00f;
}
</style>
</head>
<body>
<div class="parent">
<div class="child"></div>
</div>
</body>
</html>
In the above example, we set display: grid; place-items: end end; on the parent div, which will cause the child div to be fixed to the lower right corner of the parent div.
Using the above three methods, we can achieve a fixed div position at the lower right corner of the parent div. Choose the appropriate layout method to achieve this effect based on your actual needs and layout complexity. I hope the above content is helpful!
