How to Prevent Image Overlap on Hover Using CSS and HTML?

Fixing Image Overlap on Hover with CSS/HTML

When attempting to change an image on hover using CSS and HTML, it's not uncommon to encounter issues where the original image remains visible or the new image appears improperly scaled. Here's how to resolve this problem:

In your HTML, you have an element with the ID "Library":

<img src="LibraryTransparent.png">

And in your CSS, you have the following style rules:

#Library {
    height: 70px;
    width: 120px;
}

#Library:hover {
    background-image: url('LibraryHoverTrans.png');
    height: 70px;
    width: 120px;
}

The issue here is that while you're changing the background image for the hover state, you're not hiding the original image. To fix this, you can use the display property to make the original image invisible on hover:

#Library:hover {
    background-image: url('LibraryHoverTrans.png');
    height: 70px;
    width: 120px;
    display: block;
}

Alternatively, you can use JavaScript to change the src attribute of the element on hover:

document.getElementById("Library").onmouseover = function() {
  this.src = 'LibraryHoverTrans.png';
};

document.getElementById("Library").onmouseout = function() {
  this.src = 'LibraryTransparent.png';
};

By implementing one of these solutions, you can ensure that the original image is hidden and the new image appears correctly scaled when you hover over the image.

What is 'render-blocking CSS'? 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.
