I want to get all style properties of a specific html part(div, form, table, ...) and its children. I know how to search for style of any page element, using any browser(chrome, firefox, etc..). Should I look one by one for its children to obtain all css? Is there a way to get all css at one time related with an element and its children ?
The easiest way to do this is to use the Computed Style tab in the Chrome or Firefox web inspectors as this will allow you to see not only the explicitly defined styles of the element(s) in question but will also show you inherited styles from the cascade.
Otherwise you basically just need to copy ALL relevant style definitions from the element(s) and all of their parent and ancestor elements.

I need to apply a function to checkbox elements that are not part of a bootstrap-multiselect element. To do this I'm trying to make a css selector that fitlers out based on the parent they have. The syntax that I have so far is this:
$(this).find("input[type='checkbox']:not(ul.multiselect-container>input)")
Where the :not(ul.multiselect-container>input) is my attempt to specify to the css selector that I want all css elements except for the ones that are children of an unordered list that has the class multiselect-container.
From doing some investigation it seems that this should be possible, but my syntax doesn't seem to cut it. How can I make this work with the :not function? OR perhaps another way.
I have a list with groups in it, and use CSSOM to dynamically filter the contents using a text field. This is a way to implement a "search" using only CSS.
Unfortunately when the filter filters everything out, the group containers still remain visible. I'd need to also set display: none onto them using CSS somehow, otherwise I need to add a bunch of JS to control them.
Is this remotely possible? I know this is a big of a long shot, but is there a selector that can select elements whose children (fitting some selector) all must have a style selected on them?
Is it even possible if I greatly relax the constraints, where this might be a selector that selects elements whose children (fitting some selector) all must have a particular class?
No, it's impossible only via CSS:
There is no parent selector.
There is no visibility selector, except something like :not([style*="display:none"]):not([style*="display: none"]) if you hide elements only using inline CSS.
There is no CSS way to know if all children satisfy some condition.
This can be solved only using pure JS loops and conditions or via jQuery selectors like .parent:not(:has(:visible)).
I have some HTML as follows ( you can assume closing tags )
<ion-content>
<ion-tab>
The problem is, when the DOM is created, the HTML5 tag creates a div which I cannot edit using CSS
It becomes as so
<ion-content>
<div class="foo">
<ion-tab>
I need to edit the CSS of the div whose class is "foo", however, if i change the CSS of foo, i change the CSS of all the classes using "foo".
How do I specifically apply CSS to that specific div when I dont create it myself?
With the small amount off details you have given us, all I can do is refer to these CSS Selectors.
There are number off ways to style a specific element. All have been explained in detail in the link I have given you.
Edit: CSS Selectors explained in detail.
There are several ways to change the style of <div class="foo">.
You could give the div an (extra) #id or class. This makes it able to apply certain styles, just you would do normally, to this specify element.
Another option would be parent child {} where you could style all the children within parent. Note: you could add '>/+/~' to be more specific of the place of child within parent.
A third option would be to specify at what place the div is within its parent using :nth-child(n) or nth-of-type(n).
As I said before, there are many ways to style a specific element. Please take a look at the link I provided.
Well I wish to know how one can avoid a specific html element from getting styled by the default assigned CSS to it. Let me explain with an example:
Suppose I have an image element with it's respective default CSS assigned to it (img{}) but if I want a particular image element like logo or social icons from getting the default CSS styling then what should I do?
I know of ID's being used to target specific elements in CSS but I wish to know if their is any other way of doing this using some special markup or CSS or use of the wrapped elements like div to overcome default values. Many Thanks in Advance! :)
There is no way to prevent CSS rules with a selector that matches an element from applying to that element.
The best you can do is write more specific rules to override them with different values. You could, in browsers that support it, use the initial keyword.
I am a newbie (very much so), so my question might be dumb, but I couldn't find the answer.
For a contact table on a webpage I have set the height of 30px, but when I look at it in Google Developer tools, the height value is crossed out. I've tried to find out what causes my value to be overriden, but no luck. The developer tools shows that the value is overriden, but it doesn't show where.
So, the question is: How do I find what overrides my values in CSS?
In Chrome, your styles will inherit from any parent styles - either in the same style sheet or, if you have any, in other attached style sheets.
When a style inherits attributes either from parent elements or other classes, its predecessors will be listed in the Style Browser*, listed from nearest styles to most distant. So for example, if you have a paragraph that has a class assigned to it, but that paragraph is contained within a parent div that also has its own styles, your Style Browser will show the class name of that paragraph at the top (including all the class attributes), followed by the div's classes and so on up your DOM.
To discover which style is overriding your height value, scroll down through the Style Browser until you find a height attribute that isn't crossed out. You will also see the style sheet (including the line number) that contains the style that is affecting your page's appearance.
*You can open the style browser by right-clicking within a web page and selecting "Inspect Element".
You have to read the styles from the bottom going up.
You should find your CSS rule for the table in the styles section. Going up from that point you should be able to see which are the modifications that override your rule and display the element as depicted in the "Computed style" section.
If you dont find anything please give a look to your inline styles.
It would be easier to explain if I can look at some sample code...
The applied style is shown in the top and then the overridden ones are shown crossed out as you scroll down. So, the overridden value should be somewhere above the one which has been crossed out.
