How to position a text block over image regardless of image width

January 21, 2024

I am not well-versed with CSS and can’t figure out how to keep a text block overlay relative to the width of my image. When I change the image width from 100% to 50%, the text block stays where it’s at instead of staying "inside" the image.

This is the code I’m using:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.container {
  position: relative;
  font-family: Arial;
}

.text-block {
  position: absolute;
  bottom: 20px;
  right: 20px;
  background-color: black;
  color: white;
  padding-left: 20px;
  padding-right: 20px;
}
</style>
</head>
<body>

<div class="container">
  <img src="https://xofarragio.com/resources/graphics/placeholder_1920x1280_01.png" alt="Nature" style="width:100%;">
  <div class="text-block">
    <h4>Testing</h4>
    <p>This is a test</p>
  </div>
</div>

</body>
</html>

>Solution :

Well, it’s because your text-block div is positioned absolute to the container div, and so it is only when that element changes that the text-block div will respond. You can simply change this by changing the with of the container element, as that is the parent that controls the position of the text-block
This is the code:

.container {
  position: relative;
  font-family: Arial;
  width: 50%; /* only line added. Change wight here instead of in img*/
}

.text-block {
  position: absolute;
  bottom: 20px;
  right: 20px;
  background-color: black;
  color: white;
  padding-left: 20px;
  padding-right: 20px;
}

<!DOCTYPE html>
<html>

<head>
  <meta name="viewport" content="width=device-width, initial-scale=1">
</head>

<body>
  <div class="container">
    <img src="https://xofarragio.com/resources/graphics/placeholder_1920x1280_01.png" alt="Nature" style="width:100%;">
    <div class="text-block">
      <h4>Testing</h4>
      <p>This is a test</p>
    </div>
  </div>
</body>
