How to Override Inline !Important

.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>

External CSS !important overriding inline !important

You have apparently confused inline style origin that originates from physical HTML attribute (<el style="[css declarations]">) with in-page style sheet that has "author" level origin specificity and originates either from <style>[css rules]</style> or <link rel="stylesheet" href="[css file url]">.

Style and link elements in page are origin-wise equal, attribute is more origin-wise specific.

It is not possible to beat !important rules from inline origin level (attribute) with !important rule from author level origin.

How can I override inline styles with external CSS?

The only way to override inline style is by using !important keyword beside the CSS rule. The following is an example of it.

div {
        color: blue !important;
       /* Adding !important will give this rule more precedence over inline style */
    }

<div style="font-size: 18px; color: red;">
    Hello, World. How can I change this to blue?
</div>

#my_component {  min-width:200px;  min-height:200px;  background:red;}

<div id="my_component" class="class_1" style="width: 40px; height: 40px;"></div>

$(document).ready(function(){ $('p').removeAttr('style');  $('p').css("color","blue");});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script><p style="color:red !important;">sample text here</p>

div.selector.selectorarrow.selectorarrowleft {
  position: relative !important;
  top: 10px !important;
}
