Resizing Images to a Percentage of Themselves in CSS
Question:
How can you reduce an image's dimensions by a percentage using CSS, without resorting to JavaScript or server-side solutions, in scenarios where the original image size is unknown?
Answer:
Method 1 (Visual Resize):
This approach scales the image visually only, maintaining its original dimensions in the DOM. However, the resized image is centered within the original container.
<code class="css">img {
transform: scale(0.5);
}</code>
HTML:
<code class="html"><img src="https://via.placeholder.com/300x200" /></code>
Method 2 (Percentage-Based Background Size):
Alternatively, you can apply a percentage-based background size to a DIV element containing the image.
<code class="css">.image-container {
width: 100%;
height: 100%;
background-image: url("image.png");
background-size: 50% 50%;
background-repeat: no-repeat;
}</code>
HTML:
<code class="html"><div class="image-container"></div></code>
Note:
While Method 1 achieves the desired resizing result for a single image, Method 2 can be used to resize multiple images consistently within a container.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
