How Can I Achieve the Same Effect as CSS calc() for Width Using jQuery?

Alternative to CSS calc() using jQuery for Width with Compatibility

When working with CSS, the width: calc(100% - 100px) expression provides a convenient way to specify a desired width that dynamically adjusts based on the parent container's width. However, its compatibility issues may present challenges in certain browsers, particularly Safari.

jQuery Alternative

To address compatibility concerns and replicate the functionality of calc() using jQuery, consider the following alternative:

$('#yourEl').css('width', '100%').css('width', '-=100px');

This jQuery code achieves the same effect as calc(), dynamically setting the width of the element to 100% of its parent container and then subtracting 100 pixels. The advantage of using jQuery is that it simplifies the relative calculation, allowing you to set the width more easily and responsively. Additionally, jQuery provides cross-browser compatibility, ensuring the functionality in both modern and legacy browsers.
