How to Make vh and vw Units Work Across Browsers?

Cross-Browser JavaScript Solution for vh and vw Units

Introduction

CSS3 introduced viewport-percentage length units, vh and vw, for responsive layouts. However, these units are not fully supported across browsers. In this article, we explore a JavaScript/jQuery alternative to make vh and vw work in a cross-browser environment.

jQuery Plugin Approach

This approach involves creating a jQuery plugin that converts vh and vw values to pixel values based on the viewport size. The plugin then applies these pixel values to the desired elements. This ensures that the elements' dimensions are maintained as the viewport changes.

Example Usage

To use the plugin, you can apply it to elements using the .css() method:

<code class="javascript">$('div').css({
  height: '50vh',
  width: '50vw',
  marginTop: '25vh',
  marginLeft: '25vw',
  fontSize: '10vw'
});</code>

Browser Support

The plugin has been tested and found to work in the following browsers:

• Chrome
• Firefox
• Safari
• Internet Explorer 9
• Opera

Note on Font Sizing

While vh and vw can be used for font sizes in the plugin, it's important to note that font-size scaling may differ between browsers due to font rendering differences.

Conclusion

This jQuery plugin provides a reliable solution for using vh and vw units in a cross-browser environment. It ensures that elements retain their intended dimensions as the viewport size changes, making it an essential tool for creating responsive layouts.
