How to use links on card-img-overlay class in Bootstrap?

Last Updated : 25 Jul, 2024

When we put any link inside of a bootstrap card it performs well until we used card-img-overlay to put an image as a background of that card.

Bootstrap Card: A card in BootStrap 4 is a flexible and extensible content container. It includes options for headers, footers, content, colors, links etc.
Card Image Overlays: card-img-overlay is used to set the image as background image of the card and add text over the image. Syntax: For card overlay
```
<div class="card">
 <img src="..."/>
 <div class="card-img-overlay">
  <p class="text">....</p>
 </div>
</div>
```

Approach:

All the links placed inside class card-img-overlay works but links placed outside this class do not work. To make these links work, set the position of these links 'relative'.

CSS Code:

Place this inside the <style> tag.

.card-link 
    { 
    position:relative; 
    }

Below example illustrates the approach:

Example 1: This example illustrates card card-img-overlay, in the 1st card we are not using the card-img-overlay but when we use the card-img-overlay the links are not working even text is not responding as a text. It totally behaves likes a picture.
