Removing White Space around Scaled DIVs in CSS3

When applying a scale transformation to a DIV using CSS3, you might encounter unwanted white space around the edges of the DIV. This article explores the cause of this issue and provides solutions to eliminate it.

Understanding CSS3 Transformation

CSS3 transformations operate on rendered elements, transforming them after their initial rendering. When scaling an element, it retains its original width and height, which can leave white space around the scaled element.

解决方案

To remove the white space, consider the following approaches:

1. Adjusting CSS Dimensions

• Use the width and height properties to specify the desired dimensions of the scaled DIV. This ensures that the surrounding elements respond accordingly.
• Example:

<code class="css">.quarter.scale-thumb {
  width: 200px;
  height: 100px;
  transform: scale(0.2);
}</code>

2. Using JavaScript

• Use JavaScript to resize the scaled DIV after rendering to match the desired dimensions.
• Example:

<code class="javascript">var div = document.querySelector('.quarter.scale-thumb');
div.style.width = '200px';
div.style.height = '100px';</code>

Additional Considerations

• Scaling can affect other CSS properties, such as margins and padding. Be aware of these potential effects when implementing your solution.
• The chosen approach may depend on the specific requirements of your project, such as performance considerations and level of control required.
