Can I override the built-in? Important?

Question

If you

<div style="display: none !important;"></div> 

Is there a way to override this in the stylesheet to display it?

It is preferable to use something similar to this:

 div { display: block !important; } 

Answer 1

Let me first say that in general, inline styles can be overridden:

.override {color:red !important;}​

 <p style="color:blue;">I will be blue</p> <p style="color:blue;" class="override">But I will be red</p> 

Twisted

This description is described in the W3 specification , which states that !important declarations do not change the specifics, but rather take precedence over "normal" declarations.

Moreover, when conflicting rules have the !important flag, the specificity dictates that the built-in rule is applied - this means that for the OP script there is no way to override the built-in !important .

Answer 2

You cannot override inline CSS if it has !important . It takes precedence over style in your external CSS file.

However, if you want it to change some actions afterwards, you can use a bit of JavaScript.

Answer 3

You cannot override inline CSS with !important , since it has a higher priority, but using JavaScript, you can achieve what you want.

Answer 4

You cannot override the inline style with !important . The first preference is the inline style.

For example, we have a class

 .styleT{float:left;padding-left:4px;width:90px;} 

and in jsp

 <div class="styleT" id="inputT" style="padding-left:0px;"> 

padding-left:4px; is not taken here padding-left:4px; . It accepts a styleT class, with the exception of padding-left: 4px ;. Will padding-left:0px; .

Answer 5

Here is a simple jQuery solution.

 $(document).ready(function() { $('div').css('display','block'); }) 

Answer 6

Priority rules when two CSS properties are applied to the same node:

• !important punches not- !important . If the same! Important,...

• The style attribute is superior to CSS in the file. If both are in CSS files ...

• id in CSS selector does not beat id. And more identifiers beat less. (and you thought there were no reasons for the two identifiers in the selector.) If the number of identical identifiers ...

• Classes or attributes, such as [name] in the selector, count them; more hits less. If they are all the same ...

• tag names such as span or input , more hits less.

So you see the built-in !important is the highest priority.

Answer 7

You can see this example! There are several rules for the CSS selector. The strongest selector is built-in (if the same level with / without! Important). Following: id, class, etc. Therefore, if the tag is already stylized with inline css using! Important, you just have a way: use Javascript to change.

 var pid = document.getElementById('pid'); var button = document.getElementById('button'); button.addEventListener('click', function(){ pid.style.color = 'lime'; }); 

 p{color:violet !important;} *{color:blue !important;} html *{color:brown !important;} html p{color:lighblue !important;} .pclass{color:yellow !important;} #pid{color:green !important;} 

 <p class="pclass" id="pid" style="color:red !important;"> Hello, stylize for me ! </p> <button id='button'>Change color by JS</button>
