A simple module for fixing the height issue in mobile browsers where the address bar is visible, and the content does not fill the full height of the screen.
Is intended to solve this issue automagically 🪄

- https://css-tricks.com/the-trick-to-viewport-units-on-mobile/
From the latter of these pages I took most of the cue to create this module, so kudos to Louis Hoebregts (@Mamboleoo)
npm install mobile-height-fix
After importing the module
-
The body will be set to have a minimum height of 100% of the height of the screen
-
A new custom property will be available,
--vh
that represents the 1% of the height of the screen You can use this css variable in this way>
height: calc(var(--vh, 1vh) * 100)
Add the following script tag in the <head>
section of your HTML file to ensure that the script is executed as soon as possible:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Your Website Title</title>
<script type="module" src="node_modules/mobile-height-fix/MobileHeightFix.js"></script>
</head>
<body>
<!-- Your content here -->
</body>
</html>
If you are using a bundler or a more complex JavaScript setup, you can import the module in your JavaScript file:
// Import the MobileHeightFix class
import MobileHeightFix from 'mobile-height-fix';
// Create an instance and initialize the fix
const heightFix = new MobileHeightFix();
The MobileHeightFix
class provides a solution to the issue on mobile browsers where the address bar is visible, and the content does not fill the full height of the screen. It sets a custom property (--vh
) on the HTML root element to reflect the actual height of the viewport.
The script automatically sets the full height when it is initialized and adds a resize event listener to handle changes in viewport size.
Constructor that initializes the MobileHeightFix
instance.
Sets the full height of the window by updating the --vh
custom property on the HTML root element.
Initializes the fix by calling setFullHeight()
and adding a resize event listener.
// Import the MobileHeightFix class
import MobileHeightFix from 'mobile-height-fix';
// Create an instance and initialize the fix
const heightFix = new MobileHeightFix();
// Will update the --vh value
heightFix.setFullHeight();
The Index
script provides a solution to the issue on mobile browsers where the address bar is visible, and the content does not fill the full height of the screen. It automatically sets a custom property (--vh
) on the HTML root element to reflect the actual height of the viewport. The script is designed to work without explicit import/export and automatically sets the full height when it is loaded. It also adds a resize event listener to handle changes in viewport size.
The Index
module can be imported in more complex JavaScript setups. It provides the same functionality as the script but allows you to use modern JavaScript features like import/export. To use this option, import the module and create an instance to initialize the fix.
