Reversing Block Order with CSS Flexibility
Given the provided HTML structure, it is possible to switch the order of block elements solely using CSS, preserving the block properties. Here's a detailed solution:
CSS Media Query for Mobile Devices
To change the block order for mobile devices, employ a CSS media query that targets the maximum device width:
@media only screen and (max-device-width: 480px) {
#blockC {
order: 1;
}
}
This media query sets the order of #blockC to 1, making it the first block on the page.
Flexbox for Reordering
Flexbox is a CSS layout module that enables the reordering of child elements on the fly.
#parent {
display: flex;
flex-flow: column;
}
#blockA {
order: 1;
}
#blockC {
order: 2;
}
#blockB {
order: 3;
}
Within the #parent container, apply flexbox to allow for vertical alignment of the blocks. Then, set the order property for each block according to the desired order.
Practical Example
Here's a complete example using JavaScript:
<!DOCTYPE html>
<html>
<head>
<title>Block Reordering Example</title>
<style>
@media only screen and (max-device-width: 480px) {
#blockC {
order: 1;
}
}
#parent {
display: flex;
flex-flow: column;
}
#blockA {
order: 1;
}
#blockC {
order: 2;
}
#blockB {
order: 3;
}
</style>
</head>
<body>
<div>
This code snippet demonstrates the reordering of block elements based on screen size. Resize the browser window to see the effect of the media query in action.
