Changing Appearance of Image on Hover using CSS/HTML
You may encounter an issue where you've set an image to display a different image when the mouse hovers over, but the original image is still visible and the new image overlaps or does not change size. For beginners in HTML/CSS, this seemingly simple task can present a challenge.
To fix this issue, ensure that the original image is properly set to be transparent using a transparent image file. Additionally, check that your CSS rules are targeting the correct element using the appropriate selector syntax:
img#Library {
height: 70px;
width: 120px;
}
img#Library:hover {
background-image: url('LibraryHoverTrans.png');
height: 70px;
width: 120px;
}
However, if using CSS doesn't resolve the issue, you can consider an alternative method using JavaScript:
<img src='LibraryTransparent.png' onmouseover="this.src='LibraryHoverTrans.png';" onmouseout="this.src='LibraryTransparent.png';" />
In this JavaScript code, the onmouseover and onmouseout events are used to dynamically change the image source based on mouse interaction.

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.
