Yes its not that hard, but you should try avoid using !important all the time.
$("#tabs").css("cssText", "height: 650px !important;");
Heres a link to similar question How to include !important in jquery
Hope this helps :)
You should never need to do this. The !important flag indicates that the style should take precedence. With jQuery, you are applying the style inline to the element and therefore it already has the highest precedence.
Note that if you are using !important, you are probably doing something wrong. Consider restructuring your CSS selectors to ensure you don't need it.

I have a CSS conflict going on with a major plugin in my wordpress site. The plugin maker found it handy to add !important declarations throughout all their styling sheets. From a developer's perspective; this is a disaster. In their defense they want to cover all themes that are using !important declarations, so it looks consistent. I do not agree, so I need a solution.
What happens is that my premium theme, who's not using those declarations, cannot override the styling. I have some solutions to remove certain classes by jQuery.
But there is a problem which cannot be resolved by removing classes. For example, the anchor:hover is default as border: none !important by the plugin. But I would like to see is that the anchor:hover border option is actually applied via the theme settings. The applied CSS is this (be aware that the .plugin class is not applied in the anchor, just from a CSS file):
.plugin a { border: none !important; }
Is there any way I can disable certain class combinations from the DOM? I'm happy to have this done with php or jQuery. Something like: .plugin is not applied to anchor I have no idea how to resolve this.
Surely this is just a case of overwriting the css with a better specified css line.
For example if the code is:
.plugin a::hover { border: none !important; }
You can overwrite this by doing:
body .plugin a::hover { border: 1px solid grey !important; }
Because you have added the element body to your css line it adds extra specificity meaning it overwrites the plugins css. You unfortunately have to use !important, as !important throws regular specificity ruling out the window (bad plugin creator).
More on css specificity here
Do you need any of the styles provided by the plugin? If not then it might be worth looking at dequeueing the plugin styles altogether and just adding your own styles where the theme doesn't cover it.
If you find out the registered name of the stylesheet (should be in the style tag) you can dequeue it with something like:
function remove_push_plugin_styles() {
wp_dequeue_style( 'plugin-stylesheet' );
}
add_action( 'wp_print_styles', 'remove_pushy_plugin_styles', 1000 );
You aren't able to edit an iframe's content, true. But the iframe's itself still belongs to your page, and you can edit the attributes. I just tested and was able to do something similar to:
var i = $('div.item iframe');
// Did the selector work?
console.log(i.length);
i.removeAttr('width');
i.removeAttr('height');
That being said, using !important in this situation is not bad. If you're worried about CSS maintenance, leave a comment that the !important is overriding the element's attributes. !important is often demonized, but in this case it is a valid use to increase the specificity of your CSS.
The advantage of doing it in CSS is that it will apply before your JavaScript is loaded, so you won't get a split second of those attributes and styles applying before the JavaScript removes the styles.
I am trying to change the height of my textarea. Zurb's Foundation has already defined a height of 5rem !important.
Now, when I try to change my height using jQuery, it doesn't change. I tried:
$('textarea').height('500px')
$('textarea').css('height', '500px', 'important);
and nothing works. The CSS of any other property does change with .css(). What can I do?
If 5rem !important is set as inline style then it has the highest precedence then you can not override it by any CSS rule. You have to update the inline style then. Try this:
$('textarea').get(0).style.setProperty('height','200px','important');
From the MDN Docs
CSSStyleDeclaration.setProperty()
No return. Example: styleObj.setProperty('color', 'red', 'important')
Update:
Please read this Answer: Apply !important CSS style using jQuery
You will find really useful info there..
Happy Coding!!
Demo
You can use css - but it does not support Priority field.
Following is the correct syntax:
$('textarea').css('height','500px')
Or if you need important, you can use inline style or a class.
Demo : Add Class
.areaHeight{
height : 500px !important;
}
$('textarea').addClass('areaHeight')
There are other not-so-viable options : cssText
$('textarea').attr('style', 'height: 500px !important');
try this
<textarea id="textareaid"> </textarea>
$('#textareaid').css('height', '500px');
Try using anyone of these to set the height
Type: 1
$("textareaid").height("600")
Type: 2
$("textareaid").css("height","400px")
Make sure ur script is called after the dom element gets created
I have assigned an element a class which has following CSS:
.cls {
display:none !important;
}
When I try to show this element with jQuery
$(".cls").show();
It does not work.
How can I show this element?
$('.cls').attr('style','display:block !important');
DEMO
Although question has been asked long back but its still relevant for new coders/beginners. Generally this situation comes when you have already applied some class which overriding the display behavior using !important property.
Other answers are also relevant to the question and its a matter of achieving the same goal with different approach. I would recommend to achieve it using already available classes in the same library (bootstrap here), instead of writing custom class as these days when most of us are using Bootstrap classes to build the layout.
<div id='container' class="d-flex flex-row align-items-center">
.....
</div>
If you see in the above code, we are using d-flex class for setting display property of this container. Now if I am trying to show/hide this container using
$('#container').show()
or
$('#container').hide()
It will not work as per expectation because of
As d-flex is already using !important property
Jquery's show() method will add display:block not display:flex to the css property of container.
So I will recommend to use hidden class here.
To show container
$('#container').removeClass('hidden')
To hide container
$('#container').addClass('hidden')
2 ways of doing this,
1) Remove the !important from your .cls class,
.cls{
display: none;
}
But I assume, you'd have used this elsewhere so it might cause regression.
2) What you could alternatively do is, have a another class and toggle that,
.cls-show{
display: block !important;
}
And then in your javascript,
$('.cls').addClass(".cls-show");
Then when you need to hide it again, you can,
$('.cls').removeClass('.cls-show');
This will help you keep your markup clean and readable
!important; remove all rules and apply the css desfined as !important;. So in your case it is ignoring all rules and applying display:none.
So do this:
.cls {
display:none
}

If the only property in the CLS class selector is the display one, you can do this and don't need to add any extra classes or modify the inline style.
To show them:
$('.cls').removeClass("cls").addClass("_cls");
To hide them:
$('._cls').removeClass("_cls").addClass("cls");
Just had this exact issue, here's what I did
first, I added another class to the element, such as:
<div class="ui-cls cls">...</div>
Then in the javascript:
$('.ui-cls').removeClass('cls').show();
The nice thing is that you can also have this code to hide it again:
$('.ui-cls').hide();
and it doesn't matter how many times you hide/show, it'll still work
I'm scraping this news website: http://www.nu.nl/
If you open console and type:
$('*').css('background', 'none');
You will see all the background properties being removed, except for one which is the "blue" squire in the first article. When I trace the original CSS I see it has the !important declaration assigned to it. I don't know whether this is causing its persistence. What can I try to get rid of that blue background in terms of Jquery and Javascript or CSS?
Please note I don't want to target the element itself but rather keep using the all (*) selector or some Javascript equivalent.
jQuery doesn't recognize the !important attribute in css definitions. You just need a more specific hierarchical selector here. Simply make a new class, and then use addClass.
$('head').append('<style type="text/css">html #page .noBG{ background:none !important; }</style>');
Then just add that class to everything.
$('*').addClass('noBG');
Edit
Based on comments below, you could try
$('head').append('<style type="text/css">html body#noBG *{ background:none !important; }</style>');
Then add the ID to the body
$('body').prop('id', 'noBG');
Which is a pretty specific selector. Some rules may still pass this, and you'll have to experiment with different variations depending on the scenario.
I have found out that if we write inline css (or add it using JavaScript), then we lose the value of css hover. Is it possible to change such behavior?
Simple example
<div id="test" style="color: red">test</div>
<style>
#test:hover {
color:blue;
}
</style>
In this case hover doesn't work.
Update
I can't use !important, because after it I will not be able to change that atribute via JavaScript.
Also I generate styles dynamically, so I can't add specific classes via JavaScript.
because inline css overrides your css styles in the file
if you had
color: blue !important
it would work but not recommended, you can always use jquery to remove the inline style tag though haha
Update:
remove the style tag using jquery or when using javascript... add !important so the inline css would have important
I can't use !important, because after it i will not be able to change
that atribute via javascript.
You can still use !important, just add a class with JavaScript and remove it anytime you want.
demo
The easiest way to go is the following
$(selector).hover(function() {
$st = $(this).attr("style");
$(this).attr("style","");
},function() {
$(this).attr("style",$st);
});
In CSS, the style attribute will override any style elements or stylesheets. If you cannot change the the style attribute, you'll have to use !important. If you can remove the style attribute altogether and place everything in the style element. Or even better, in a separate stylesheet your problem will be fixed.
P.S. The type attribute is required on style elements. This won't fix your problem, but you should change <style> to <style type="text/css">
