I am trying to develop something where I need this requirement, I tried a couple of things, but not able to do it.
There is one style - A:
.someClass {
padding-right:10px;
}
now I want to add margin also in same class like - B:
.someClass {
margin-left:10px;
}
Now I need both, padding and margin. The thing is I can't modify A as it set by some third party JS, which doesn't reside locally.
So, is there any way I can achieve this by Pure CSS or JS (NO Jquery)
There is one style - A:
.someClass {
padding-right: 10px;
}
No, that is not a "style". That is a "rule". It says to apply padding-right to elements with the someClass class.
Now you add another rule:
.someClass {
margin-left: 10px;
}
That says to apply margin-left to elements with the someClass class.
Together the two rules do exactly what you want. The key point is that CSS will apply all rules whose "selectors" (here, the .someClass part) match the element in question. If the two rules contain the same properties, then there are ways (involving concepts such as "precedence" and "specificity") in which CSS will choose which one to apply, but that is not the case here, so both padding-right and margin-left will be applied to elements with the someClass class.
You can put both margin and padding into the element at once:
.someClass{
margin: 10px;
padding: 10px;
}
Also if the margin or anything else is set by like you said third party JS you can Override it in CSS by adding: !important so your code would look like this:
.someClass{
margin: 10px !important;
padding: 10px !important;
}
According to your question you need only padding to override.
Hope i understood your Question and could help.

There's a certain CSS property that I want to remove, but I can't because it is auto-generated by a backend engine called Pelican.
.rendered_html ul:not(.list-inline) {
padding-left: 2em;
}
I want to remove this property, but I don't know how. Here's the screenshot
In a Chrome developer tool, if I uncheck that property, it works fine, but if I leave it as it is, it looks bad. And the thing I don't understand is that both appear as greyed out in chrome developer tool, and yet they seem to have effects on the CSS property. To my understanding, if the properties are greyed out, they should not have any effects, but in this case they do.
I tried doing this:
.rendered_html ul:not(.list-inline) {
padding-left: unset !important;
}
But this is not what I want because I want it, because I also want to add this property:
ul.ascii {
padding: 1rem;
}
Unsetting the padding by adding additional CSS codes in my .css file will prevent me from applying padding: 1rem property.
How can I nullify the css proprety of .rendered_html ul:not(.list-inline) ?
not ideal, but
.rendered_html ul:not(.list-inline) {
padding-left: 0 !important;
}
.rendered_html ul.ascii {
padding: 1rem !important;
}
will likely solve your problem.
the adding of the extra step .rendered_html on the second instruction gives it the same specificity hierarchy as the first one, so it wont be ignored.
you might not need !important depending on .css loading order, so try to change that too.

I'm trying to remove the value of an inherited CSS property using Jquery.
.class1 #id1 div.class2 input.class-input{
border-color: #bbb3b9 #c7c1c6 #c7c1c6;
}
Anyone tell me how to remove this "border-color".
Thank.
Create a new class for example
.new_class{
border-color: #00ffdd !important;
}
!important does the trick!
Check this
You can use jQuery, but you'll have to assign a value to the border-color property. You can use transparent though:
$('.class-input').css('border-color', 'transparent');
Edit: Or you can disable the whole border:
$('.class-input').css('border', 'none');
You can either swap the on your div to change the color, or set the border color to empty using
$(".class1").css("border-color", "");
But I would recommend swapping out the class using the removeClass and addClass JQuery functions.
If you still want to keep the width of the border:
border-color: transparent;
If you want to remove the border all together
border: 0;
Edit: border: none; will give your the same result
So your jquery could look something like this:
$(".class-input").css("border","0");
However I would suggest using CSS if you don't need to make it animated. Since you raised the concern about .class1 #id1 div.class2 input.class-input.myclass (I'm assuming that's what you mean since you wouldn't be throwing a div into an input box.
You can use the CSS pseudo-selector :not
.class1 #id1 div.class2 input.class-input:not(.my-class){
border: 0;
}
The simplest way to handle this is to add another reference to give your override code a higher specificity.
.class1 #id1 div.class2 input.class-input [#MyNewID]{
border: none;
}
This removes the border for the area where you have added the ID so that if you are using this same format in other pages you can add an additional ID on the element on the page where you want the border to "disappear"
Please don't use !important this is a lazy way to override code and is not necessary 95% of the time. It will also cause you problem later when you are trying to change this if you are pushing down site wide skins.
I have an input element:
<input id="box" type="text" />
And the following CSS class:
.box-change
{
border-color:#ffffff;
}
As well as the following jQuery code:
$('#box').toggleClass('box-change');
However, it doesn't change the border color as I expect it to. Does anyone know why?
Edit:
The input already has a style, it is thus:
#box
{
border-color:#ff0000;
border-style:solid;
border-bottom-width:1px;
border-left-width:1px;
border-top-width:1px;
}
If you've originally removed border, then you'll have to set
border-width
and
border-style
So in short your CSS should look like:
.box-change
{
border: 1px solid #fff;
}
But it all depends what your initial style is, what colour is background of the containing element of your input etc...
Edit after you've provided more detail
your class doesn't get applied because class that sets style by ID has higher priority in cascade than CSS class. That's the main reason why you're not seeing it applied.
If you'd like your CSS class to take over you have two options:
set it as important:
.box-change
{
border: 1px solid #fff !important;
}
provide CSS rule that has higher specificity and will take over
#box.box-change
{
border: 1px solid #fff;
}
The second way is the preferred way, because using !important will make your CSS harder to maintain, since your classes don't cascade as per CSS but rather as per your importance. And you can easily loose control over that. Avoid important unless on seldom occasions.
How to troubleshoot this?
To help you in the future, you should be using developer tools in browser (Chrome DevTools or Firebug for Firefox) that would immediately show you the problem. And of course understand CSS specificity rules and how they cascade.
As your original styles are defined with #box it is more specific than .box-change, and by default overrides your new additions. It could also be that .box-change is higher up the cascade than #box.
You could solve it one of two ways:
#box.box-change{
border-color: #fff;
}
or
.box-change{
border-color: #fff !important;
}
I am doing a code that do some js injection of code in page, with JQuery. But in my input that i get in some pages modify it, I am putting all important attributes and define them as !important, but it's impossible to put all the attributes in all the tags.
Someone know how to disable all other css inside a div?
Solution I think:
I found a solution but i don't want to use it. Its eliminate al css from the page, while i am injecting the code after using that code I eliminate my css and code and apply the original code from the webpage
Thanks
If you're using that many !importants you're doing it wrong.
The solution to this problem is to properly organize your css. Important stuff last, because it overrides what was previously styled. Also use your selectors wisely. Example:
<a class="link">Link</a>
.
a:link { color: red; }
.
.
.
.link { color: green !important; } // Nop
a.link { color: green; } // Yup
If you override everything it will work with normal CSS rules on every page. Not what you were hoping for, but it is a solution.
css:
#myInsertDiv {
color: blue;
padding: 0;
margin: 0;
background: white;
border: 0px;
/* etc you have to restyle EVERY possible value */
}
html:
<div id="myInsertDiv"></div>
The main issue is you have to style every attribute, and reset everything else to a default value.
Or you can insert all the style information into the style attribute on the div, but that is probably doing it wrong too.
If I got you right you can use jQuery for modifying CSS properties on any elements of the page (huh), using something like this $('.Myclass').css('color','#ff0000')

How to reset/remove CSS styles for a specific element or selector only
(17 answers)
Closed last month.
I know this question was asked before, but before marking it as a duplicate, I want to tell you that my situation is a little different from what I found on the internet.
I'm building and embedded script that people can put it on their sites. This script creates a div with a certain width/height and some information in it.
My problem is that some websites declare styles for div that are inherited by my div as well.
for example:
div{
background-color:red;
}
so if I don't set any background color to my div, it will show red even if I don't want that.
The only solutions I come along is to overwrite as many css proprieties, this way my div will show exactly as I want.
The problem with this solution is that there are too many css proprieties to overwrite and I want my script to be as light as it can be.
So my question is if you know another solution to my problem.
It can be in css/javascript /jQuery.
Thanks
"Resetting" styles for a specific element isn't possible, you'll have to overwrite all styles you don't want/need. If you do this with CSS directly or using JQuery to apply the styles (depends on what's easier for you, but I wouldn't recommend using JavaScript/JQuery for this, as it's completely unnecessary).
If your div is some kind of "widget" that can be included into other sites, you could try to wrap it into an iframe. This will "reset" the styles, because its content is another document, but maybe this affects how your widget works (or maybe breaks it completely) so this might not be possible in your case.
Only set the relevant / important CSS properties.
Example (only change the attributes which may cause your div to look completely different):
background: #FFF;
border: none;
color: #000;
display: block;
font: initial;
height: auto;
letter-spacing: normal;
line-height: normal;
margin: 0;
padding: 0;
text-transform: none;
visibility: visible;
width: auto;
word-spacing: normal;
z-index: auto;
Choose a very specific selector, such as div#donttouchme, <div id="donttouchme"></div>. Additionally, you can add `!important before every semicolon in the declaration. Your customers are deliberately trying to mess up your lay-out when this option fails.
You could try overwriting the CSS and use auto
I don't think this will work with color specifically, but I ran into an issue where i had a parent property such as
.parent {
left: 0px;
}
and then I was able to just define my child with something like
.child {
left: auto;
}
and it effectively "reset" the property.
Technically what you are looking for is the unset value in combination with the shorthand property all:
The unset CSS keyword resets a property to its inherited value if it inherits from its parent, and to its initial value if not. In other words, it behaves like the inherit keyword in the first case, and like the initial keyword in the second case. It can be applied to any CSS property, including the CSS shorthand all.
.customClass {
/* specific attribute */
color: unset;
}
.otherClass{
/* unset all attributes */
all: unset;
/* then set own attributes */
color: red;
}
You can use the initial value as well, this will default to the initial browser value.
.otherClass{
/* unset all attributes */
all: initial;
/* then set own attributes */
color: red;
}
As an alternative:
If possible it is probably good practice to encapsulate the class or id in a kind of namespace:
.namespace .customClass{
color: red;
}
<div class="namespace">
<div class="customClass"></div>
</div>
because of the specificity of the selector this will only influence your own classes
It is easier to accomplish this in "preprocessor scripting languages" like SASS with nesting capabilities:
.namespace{
.customClass{
color: red
}
}
Try this: Create a plain div without any style or content outside of the red div. Now you can use a loop over all styles of the plain div and assign then to your inner div to reset all styles.
Of course this doesn't work if someone assigns styles to all divs (i.e. without using a class. CSS would be div { ... }).
The usual solution for problems like this is to give your div a distinct class. That way, web designers of the sites can adjust the styling of your div to fit into the rest of the design.
As long as they are attributes like classes and ids you can remove them by javascript/jQuery class modifiers.
document.getElementById("MyElement").className = "";
There is no way to remove specific tag CSS other than overriding them (or using another element).
you may use this below option.
<style>
div:not(.no_common_style){
background-color:red;
}
</style>
now , if their any place where you do not want to apply default style you can use 'no_common_style' class as class.
ex:
<div class="no_common_style">
It will not display in red
</div>
From what I understand you want to use a div that inherits from no class but yours. As mentioned in the previous reply you cannot completely reset a div inheritance. However, what worked for me with that issue was to use another element - one that is not frequent and certainly not used in the current html page. A good example, is to use instead of then customize it to look just like your ideal would.
area { background-color : red; }
One simple approach would be to use the !important modifier in css, but this can be overridden in the same way from users.
Maybe a solution can be achieved with jquery by traversing the entire DOM to find your (re)defined classes and removing / forcing css styles.
