Understanding object-fit: contain and Image Resizing
When using CSS object-fit: contain to make images responsive within flexbox containers, it's essential to understand how this property affects image width. Despite the resizing of images, the layout might retain the original image size, resulting in a scrollbar.
In object-fit: contain, the image is scaled proportionally so that the entire image remains within the specified container while preserving its aspect ratio. This ensures that the image is fully visible and avoids cropping. However, it doesn't necessarily resize the image to fit the width of its container.
To address this, you need to set the CSS width property of the container to a specific value or percentage that you want the image to be displayed at.
For example, if you have the following HTML:
<code class="html"><div class="container"> <img src="image.jpg" /> </div></code>
And the following CSS:
<code class="css">.container {
width: 50%;
height: 50%;
}
img {
object-fit: contain;
}</code>
The image will be scaled proportionally to fit within the .container, but the width of the image will remain its original size. To fit the width of the container, you can specify the width of the .container as a percentage or absolute value:
<code class="css">.container {
width: 100vw; // 100% of the viewport width
}
// or
.container {
width: 500px; // 500 pixels
}</code>
Remember, object-fit: contain only ensures that the image is visible within the container without cropping. If you need to resize the image specifically to the width of the container, you need to set the width property of the container accordingly.

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.
