I have some components which use the mat-tab elements in the HTML. When trying to style these elements in the CSS, I am only able to style them using ::ng-deep .mat-tab-label {} for example, and putting !important next to at least one of the style changes. I do not want to leave this in the application long-term, especially after reading this article.
Here is how it breaks down looking at the elements in developer tools:
<mat-card class="mat-card">
<mat-tab-group class="mat-tab-group mat-primary">
<mat-tab-header class="mat-tab-header">
<div class="mat-tab-header-pagination mat-tab-header-pagination-before mat-elevation-z4 mat-ripple mat-tab-header-pagination-disabled>
<div class="mat-tab-label-container">
<div class="mat-tab-list">
<div class="mat-tab-labels">
<div class="mat-tab-label mat-ripple mat-tab-label-active ng-star-inserted">
<mat-ink-bar class="mat-ink-bar">
What can I do in order to style these elements without using ::ng-deep and !important in the CSS?

and !important in the CSS?
In this case the solution that you can do is to use Selector specificity and then put your style in the root style /src/styles.css
(NOTE: that don't put it in the components styleUrls your style will not work)
/* label style */
.mat-tab-label{
background: green;
color:white;
}
/* focus style */
.mat-tab-group.mat-primary .mat-tab-label:not(.mat-tab-disabled):focus, .mat-tab-group.mat-primary .mat-tab-link:not(.mat-tab-disabled):focus, .mat-tab-nav-bar.mat-primary .mat-tab-label:not(.mat-tab-disabled):focus, .mat-tab-nav-bar.mat-primary .mat-tab-link:not(.mat-tab-disabled):focus{
background: red;
}
/* ink bar style */
.mat-tab-group.mat-primary .mat-ink-bar, .mat-tab-nav-bar.mat-primary .mat-ink-bar{
background: yellow;
height: 10px;
}

my website scraped information from ebay products and for the description of the product I get all html. Product description has inline styles and when I open the description of the product in my website, products css ovewrite my css
Normal:
And after I opened the product description
Here is anchor style from developer tool
So I need any idea how to separete ebay product css with my css.
One of the methods that I think is to add !important to all my styles, but I don't think this solution is elegant and I want something else. So If you have any suggestion how to solve my issue I will appreciate them.
Perhaps you need to update your css to be more specific with it's selector, for example if you have a HTML structure which diferentiate the container of the Product Description from eBay like this
.leftbar {
float: left;
width: 20%;
background: #ccc;
}
a { /*think of this as default link style*/
color: black;
}
#main div:not(.product-desc) a { /*more specific selector*/
display: block;
color: red;
}
a { /*this one is from eBay*/
color: green;
}
<div id='main'>
<div class='leftbar'>
<a>Hello</a>
<a>World</a>
</div>
<div class='product-desc'>
<a>Description</a>
<a>Product</a>
</div>
</div>
You can use a :not selector to define your main style so it won't be disrupted by the eBay style
The more specific your selector is, then your style will be used. But if your selector is the same, then the last rule from top bottom will be applied. So in the above example, the link inside product-desc color is set to green not black
create a custom inline CSS property that you desire in the element to overwrite the default CSS. here is how you create inline CSS for overwriting anchor properties.
Here how you do:
create the icons/text of anchor inside a element and give inline CSS
<a href="http://www.example.com" target="_blank">
<span style="color: #ffffff !important;" >icons</span>
</a>
A quick test in Chrome shows that the
a:visited * { ... !important}
does override the inline style, but adding the !important back to the span works fine.
<span style="color: #ffffff !important;" >

Overwriting visited in anchor
Blockquote
If you want to remove all exist style and reset it to default you can use:
all: initial;
I have defined this hover for div element
div.MyCSSClass:hover
{
background-color: purple;
}
This is my HTML source:
<div class="
<ul class="MyParentCSSClass">
<li>
<div>
<div>
<div class="MyCSSClass">
<!-- I want to remove CSS hover for this div element -->
I want to remove the hover when the div.MyCSSClass is a child of MyParentCSSClass, So I add this to remove the hover style in CSS:
.MyParentCSSClass div.MyCSSClass:hover
{
}
But it did not work. I still see the same hover style.
Is there a way to remove hover in CSS without me creating a new CSS class for my div tag? I want to keep the same name as I have other CSS property uses the 'MyCSSClass'.
Thanks for the suggestion. I tried
background-color: none !important;
But when I look into chrome, that CSS is being over-written by
.MyGrandParentClass div.MyCSSClass:hover
{
background-color: purple;
}
and the html source is
<div class="MyGrandParent">
<ul class="MyParentCSSClass">
<li>
<div>
<div>
<div class="MyCSSClass">
<!-- I want to remove CSS hover for this div element -->
My question is how my 'Remove hover' css rule is being over-written? I have put "!important" to my rule.
.MyParentCSSClass div.MyCSSClass:hover {
background-color: none;
}
This will overwrite the background color given by div.MyCSSClass:hover. if you are keeping MyParentCSSClass div.MyCSSClass:hover empty as MyParentCSSClass div.MyCSSClass:hover {}, it will not overwrite anything or doing nothing actually.
You need to re-write all the previously added styles to the hover event. In the case you specified, please do the following:
.MyParentCSSClass div.MyCSSClass:hover
{
background-color: none;
}
Background-color : none; is not w3c standard. It will work on some browser but according to w3c standard it's not right way.
So try to use background-color: transparent which will work good on all browsers and w3c can validate your code.
Have fun.
I'm using the ReStart Bootstrap template in an ASP.NET MVC application and have applied a bunch of CSS overrides in a child stylesheet. For some reason, not all of the overrides are taking effect in my Chrome browser, though I'm positive the selectors are all named correctly. I've also placed the link to the child stylesheet after the link to the parent sheet in my HTML markup to ensure it loads in the correct order.
Here's an example where-in I am merely changing the background color of a single element:
Parent styling as it appears in style.css sheet:
#social_media_wrapper {
background: #428bca;
}
Child styling in site.css sheet:
#social_media_wrapper {
background: #ff8000;
}
Here is the element's HTML reference:
<div id="social_media_wrapper">
<i class="fa fa-linkedin-square"></i>
</i>
<i class="fa fa-github-square" target="_blank"></i>
</div>
Not sure what else would be missing here that would cause these child stylings to be ignored by the browser, as there is nothing in the parent styling marked !important that would prevent a child styling from overriding (especially since other child styles that live in the same document are overriding their parents without any issue).
Change :
#social_media_wrapper {
background-color: #ff8000 !important;
}
I hope this might help.
Change
#social_media_wrapper {
background: #ff8000;
}
to
#social_media_wrapper {
background-color: #ff8000;
}
When I want to apply a certain style to a div (specially using bootstrap 3), I create my own class like this:
.myClass {
width: 30%;
padding-right: 0px;
}
<div class="myClass"></div>
But sometimes the div style is overwritten by the bootstrap classes or another inherited properties (I don't understand completely the inheritance in CSS3), but if I apply directly in the div:
<div style="width: 30%;padding-right: 0px;"></div>
2 ways to force CSS on an element in this case :
You have you custom CSS located in a local .css file : put the <link> tag for this custom stylesheet after the Bootstrap css file.
Set the CSS rule !important after each properties so they will get an extra authority upon others
CSS inheritance
.myClass is less than div.myClass which is less than body div.myClass.
The Bootstrap is using usually more than one identifier. Like .ourClass.theirClass.yourClass which is hard to overwrite. Inspect your element in your browser to see the inheritance and try to overwrite it the css way before using any !important attributes.
The last rule defining a style of the element will be aplied to it.
So if you have various stylesheets in your page, the order of the files should be in the order you want them to be applied. example:
<link rel="stylesheet" href="style.css">
<link rel="stylesheet" href="secondStyle.css">
Every style rule(not an entire block) that is written in the second file will be the definitive one in the website.
the same rule apllies within files, for example:
.ClassOne {
color: red;
}
... othes styling ...
.classOne {
color: Black;
}
In this case the color in the browser will be Black because it was the last one and it overwrites the first one.
There is another rule that can affect styling - The more specific rule will be the definitive one, example:
.one .two .three {
color: red;
}
.two .three {
color: blue;
}
.one .three {
color: green;
}
<div class="one">
<div class="two">
<div class="three">
some text
</div>
</div>
</div>
Question: In which color will the text show?
Answer: red.
Why? because in the case above, we call the .three element in a more specific way when we declared the red color.
check it here:
https://jsfiddle.net/wxaw3205/
The same example with more elements:
https://jsfiddle.net/wxaw3205/1/
The last way is using the !important declaration, it provides a way for You to give a CSS value more weight than it naturally has.
For the last example, lets assume that we have the same html markup of the example above, which will be the color now?
.one .two .three {
color: red;
}
.two .three {
color: blue;
}
.one .three {
color: green !important;
}
Answer: green.
Link to live example: https://jsfiddle.net/wxaw3205/2/
And just a little tip: never style the element using the style="" attribute, unless you have too! and either the !important.
Most of the time when you have to use them its because you'r stylesheet needs to be reordered.
That's all, I hope it helped you understand.
I'm trying to place a link in Wordpress quickly and we have a pretty complex style being applied to all a href links in the section. Here's a small sample of the selector and the styles within (there's about 40 lines of styles which I held back)
div.content-rotator li.featured-content a {
margin: 0px;
border: 1px solid rgb(34,56,19);
}
Is there anyway I can place a link in this li and override the parent style? It has to appear within the li with class featured-content.
I don't want to touch the existing CSS at this stage so I'd prefer to implement inline styles on the a element.
Thanks
EDIT: Just in case it wasn't clear, the CSS above is coming from the style sheet and I'd like to zero it out.
There's > 50 lines of styles in this though, I've only shown two for brevity so inline replacing them all isn't really an option.
Just use inline styles or/and add !important to overriden CSS definition, like:
<div class="content-rotator">
<ul>
<li class="featured-content">
...
</li>
</ul>
</div>
or
div.content-rotator li.featured-content a.other {
margin: 3px !important;
border: none !important;
}
Give the selected link an ID and just add !important to the styles. I don't think there is a better alternative unless you plan to go through the entire stylesheet.
