I have a stylesheet which has the following property,
.primary-nav .suppa_rwd_button, .primary-nav .suppa_rwd_button span{
color:#FFFFFF!important;
}
I can't edit the stylesheet. How do I change the property to
color:#000000!important;
I tried to write the following code in another stylesheet,
.primary-nav .suppa_rwd_button, .primary-nav .suppa_rwd_button span{
color:#000000!important;
}
but it did not work. Please guide. Thanks.
Other than Emmanuel's answer which talks about this: CSS Specificity, You can also try using two approaches:
Change order of stylesheet
Make sure your other stylesheet order is higher than the current version. That is include the new stylesheet link after the stylesheet which is to be overridden
<link rel="stylesheet" href="style.css">
<link rel="stylesheet" href="style1.css"> <!-- Styles that will overwrite -->
Inline HTML
If you can change your HTML, you can use this:
<span style="color: #000000 !important;">
!important in inline style will have higher priority than in other types of styles.
Did you try using:
.primary-nav .suppa_rwd_button span{
color:#000000!important;
}
Other way could be using JavaScript:
Override using JavaScript
$('.mytable td').attr('style', 'display: none !important');
Cheers!
In order to override an !important rule you have to put a same specific rule after the previous one or to increase specificity of new rule as:
nav.primary-nav li.suppa_rwd_button, nav.primary-nav li.suppa_rwd_button span{
color:#000000!important;
}
* suppose that .primary-nav is a nav element and .suppa_rwd_button a li element, you could change them due to your markup.
In both cases you have to also use !important in your new rule.

On my layout page, in the <head>, I have the following styles:
<link rel="stylesheet" href="/dist/vendor.css">
<style>
.bg-dark {
background-color: #240000;
}
</style>
I have added the link to my layout page. The style block is added dynamically by Angular & webpack. From what I know about CSS, that last .bg-dark class should win over any .bg-dark class declared in `vendor.css. Yet I see the following:
Is this something caused by the magical pre-rendering of Angular? Is there some way to prevent this?
The background-color attribute in vendor.css has the !important flag, which elevates its priority:
background-color: #222222 !important;
To override that setting, you should set the !important flag in your layout page CSS:
<style>
.bg-dark {
background-color: #240000 !important;
}
</style>
or remove that flag in vendor.css, if your can.
I have a CSS file with some div styles and this CSS has a body, like this:
css1.css
body{
background-color:#000;
}
#div1{
...
}
#div2{
...
}
in a page I want to use some divs that are in css1.css but with a different body color.
So I create another css for this:
css2.css
body{
background-color:#fff;
}
so in this page I have:
<link rel="stylesheet" type="text/css" href="css1.css">
<link rel="stylesheet" type="text/css" href="css2.css">
css1.css has a body and css2 too, is it right? Can I have any problem doing this?
You don't need all that, you can simply set different background colours to the divs. You can give them different IDs or classes and work your css around that.
HTML:
<div id="one">this is div one</div>
<div id="two">this is div two</div>
CSS:
div#one { background-color: blue; }
div#two { background-color: red; }
You could also change your body with different classes on different pages that consume the same CSS. I hope this solves your problem.
It is OK. The last declaration will take precedence over the first, assuming the selectors are the same.
Yes you can!
Although you may need to look at css selector specificity:
https://developer.tizen.org/dev-guide/web/2.3.0/org.tizen.mobile.web.appprogramming/html/guide/w3c_guide/dom_guide/html_priorities_css.htm. Here is a more illustrated resource:
from https://css-tricks.com/specifics-on-css-specificity/
The specificity depends on the number of tags, ids, classes, pseudo-classes etc that are contained in your selectors. If there is a tie between selectors then the order matters.
Those two selectors (for body) have the same specificity (=0001) so the second one will override the common properties of the first.
Or in other words the body background-color will be #fff :). If that is useful to you is a different question.
Is it possible to style a custom element with an external css file that is linked on the index page but not in an element itself. I haven't found any documentation about using a css file not within the element itself.
I have something like this example.
<head>
/* Use of only 1 css for all elements */
<link href="css/custom.less" rel="stylesheet/less" type="text/css">
</head>
<body>
<my-element></my-element>
<my-other></my-other>
<my-other2></my-other>
</body>
The problem is that the styling has been done in Firefox but not in Chrome.
So I know it's not a problem with the css.
Css looks something like this.
my-element {
header {
background-color: #article-color;
text-align: center;
margin-bottom: 25px;
h1 {
color: #ffffff;
}
}
}
/* Styling of other elements */
I know I can use css within the polymer element itself, but I don't want to do this. I have multiple elements and I want to style all of them within one css file that I link in the index file like in the example.
It is possible to style custom elements from the index file using a ::shadow or the /deep/ pseudo-element.
Example:
<head>
<style>
// This is thinking there is a 'p' in 'my-element'
my-element::shadow p{
color: red
}
</style>
</head>
<body>
<my-element></my-element>
</body>
But please know this before you use it,according to the Polymer docs this method is not very efficient in execution, meaning it could potentially slow the rendering of the page if used a lot.

I am using Bootstrap CSS on my site and am loading in the <head> element. Just below I load the boostrap I have a <style> element where I am trying to override some CSS from the bootstrap, but it is not overriding it when I look at the Chrome Dev Inspector. I thought elements in element should cascade the previous ?
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<title>Women's Transit</title>
<!--<script src="https://cdnjs.cloudflare.com/ajax/libs/normalize/3.0.1/normalize.min.css" type="text/javascript" />-->
<link rel="stylesheet" href="/CS483-Final/content/bootstrap/css/bootstrap-responsive.css" type="text/css" />
<link rel="stylesheet" href="/CS483-Final/content/bootstrap/css/bootstrap.css" type="text/css" />
<style type="text/css">
/* Global elements */
input {
height:30px;
padding:8px;
}
</style>
</head>
You probably want !important.
input {
height: 30px !important;
padding: 8px !important;
}
https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity
Specificity is the means by which a browser decides which property values are the most relevant to an element and gets to be applied. Specificity is only based on the matching rules which are composed of selectors of different sorts.
Important:
When an !important rule is used on a style declaration, this declaration overrides any other declaration made in the CSS, wherever it is in the declaration list. Although, !important has nothing to do with specificity. Using !important is bad practice because it makes debugging hard since you break the natural cascading in your stylesheets.
So !important is the easiest way to override styles, because it is more "specific" than other styles. Please note that overriding styles is very bad practice, especially with !important.
The actual solution: Don't override styles.
The internal or embedded style you created would have a higher "order of importance" than Bootstrap's and cascade over their styles ONLY if the same selector was used in Bootstrap's sheet with the same weight and selectivity. That's not likely the case because they use classes to modify most styles. The "input" element has a weight of 1, so if they use classes with those properties they would easily cascade over your element style (a plain class generally has a weight of 10).
Bootstrap does use an "input" style in their reboot element style sheet, so your sheet would likely cascade over that one style. But I don't see them changing height or padding there so your styles would apply until their custom class changes its property styles further. In addition, their input style changes things you don't, like "margin" and "line-height" which might be affecting your layout further.
My advice is to NOT use "input" or "!important" and instead create a custom class and add the class to your element. Make it more selective than Bootstrap's with a full set of properties so you cascade over Bootstrap's input and class styles but inherit some things you like. This gives you full control now over what you like and don't like in Bootstrap:
body form .myinput{
width:100px
height: 30px;
padding: 8px;
margin: 0;
font-family: inherit;
font-size: inherit;
line-height: inherit;
}
<input class="myinput ..." />
The downfall of most young web developers with CSS is they do not add enough style properties to their styles and rely on either inherited or unknown changes to be cascading down into their elements. Adding a full set of properties gives you total control over how that element looks and what it inherits.
The mystery is gone :)
I like to have the navbar-inner element in my Bootstrap Layout to be customizable by the jQuery UI framework.
<div class="navbar-inner ui-widget-header">
</div>
But the background of the navbar is always black.
How can overwrite the Bootstrap Background with the background from the ui-widget-header class without changing the bootstrap css file?
Create your own CSS file which you will use to overwrite styles from the bootstrap.css and add its reference to your HTML after the reference to bootstrap.css. Also, to ensure that your styles overwrite the bootstrap ones you can use the !important keyword in your css.
So, create a CSS file and call it something like bootstrap-overwrite.css.
Add the bootstrap class you want to overwrite -
.navbar-inner
{
background: none !important;
}
Add the reference to your HTML after the bootstrap reference -
<link href="styles/bootstrap.css" rel="stylesheet" type="text/css" />
<link href="styles/bootstrap-overwrite.css" rel="stylesheet" type="text/css" />
Twitter Bootstrap is a framework that is supposed to be restyled so you shouldn't be afraid of overwriting the default styling.
Make the ui-widget-header selector more specific, so that it overrides navbar-inner in the cascade. For example,
#pageid .navbar .ui-widget-header {
background: red;
}
Is more specific than simply...
.ui-widget-header {
background: red;
}
