We all know that we can not apply a important CSS property directly to an element. It does not work. But still there is a solution for that. Here I am going to share you that. I hope you will like this.

Background

Recently I was going through a situation that to apply a custom CSS to an element which already has some CSS styles and all. I wanted to overwrite those CSS in situation based, that is when some condition satisfies.

Using the code

First of all we will create a page and some div element.

[html]
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>CSS Important In JQuery</title>
<script src="jquery-2.0.2.min.js"></script>
</head>
<body>
<div id="container">
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
</div>
</body>
</html>

[/html]

You an see that I have loaded a JQuery reference and added some in-line CSS to the elements. As you all know, even if we give a custom css as follows

[css]
<style>
#container div {
width:55px;
}
</style>
[/css]

The width will be 25px, because we have set the in-line css as

[html]
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
[/html]

Now if you run your page and, check your browser console you can get to know that.

In this situation, we use !important tag in the css, So if you change your css styles as follows, you can see your new css is getting applied.

[css]
<style>
#container div {
width:55px !important;
}
</style>
[/css]

Now refresh your page and see the browser console.

Now what if you need to change this CSS, when there is a jquery action. For example you need to change the css styles when user clicks on an element? Cool, we have a solution for that too. Now you will be thinking the solution is as follows.

[js]
<script>
$(function () {
$(‘#click’).click(function () {
$("#container div").css(‘width’, ’75px;!important’);
});
});
</script>
[/js]

Here #click is my a href.

[html]
<a href="#" id="click">Click</a>
[/html]

If you run that, you will know it didn’t work. No worries, I am going to share you a solution for this.

Now we will change our script as follows.

[js]
<script>
$(function () {
$(‘#click’).click(function () {
//$("#container div").css(‘width’, ’75px;!important’);
$("#container div").each(function () {
this.style.setProperty(‘width’, ’75px’, ‘important’);
});
});
});
</script>
[/js]

And it is tie to run our page now.

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>CSS Important In JQuery</title>
<script src="jquery-2.0.2.min.js"></script>
<script>
$(function () {
$(‘#click’).click(function () {
//$("#container div").css(‘width’, ’75px;!important’);
$("#container div").each(function () {
this.style.setProperty(‘width’, ’75px’, ‘important’);
});
});
});
</script>
<style>
#container div {
width:55px !important;
}
</style>
</head>
<body>
<div id="container">
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
<div style="width: 25px;height: 28px;padding: 5px;background-color: green;margin: 3px;float: left;cursor: move;" ></div>
</div>
<a href="#" id="click">Click</a>
</body>
</html>

[/html]
