(Attempting to modify CSS properties within a Chrome extension content script)
Is it feasible to override CSS properties that have been marked as !important on the webpage?
For example, if I aim to eliminate an important border:
$(".someclass").css('border','none'); //this approach does not yield the desired result
Here is a solution for you:
$( '.someclass' ).each(function () {
this.style.setProperty( 'border', 'none', 'important' );
});
Check it out in action: http://jsfiddle.net/Gtr54/
The .setProperty method of an element's style object allows you to specify the priority when setting a CSS property. This means you can override an existing !important value with your own !important value. While jQuery does not provide a way to set the !important priority directly, you can achieve this using the native .setProperty method.
Another way to achieve the same result is:
$(".someclass").css("cssText", "border: none !important;");
This advice should come in handy.
$(".specialclass").attr("style","border:none!important");
Revised to prevent replacing all styles:
var currentStyles = $(".specialclass").attr("style");
$(".specialclass").attr("style", currentStyles+"border:none!important");
Adding a class with jQuery is simple
$("exampleclass").addClass("highlight");
<style>
.highlight{
border:none !important;
}
</style>
Another method can also be used
$("#m_divList tbody").find("tr[data-uid=" + row.uid + "]").find('td').css("cssText", "color: red !important;");
css("cssText", "color: red !important;");
Follow this example to effectively override styles using jQuery.
<style>
div.woocommerce-variation-add-to-cart-disabled {
display: none ! important;
}
</style>
<div class="woocommerce-variation-add-to-cart variations_button woocommerce-variation-add-to-cart-disabled">
<script>
jQuery(document).ready(function() {
jQuery('.woocommerce-variation-add-to-cart').attr('style', 'display: block !important;');
});
</script>
</div>
