How to apply font size attribute to ul marker without afftecting list content's font size

I am using a contentEditable div to add my contents. i set the font size, color, face and bullets from my UI using javascript(script#).
I apply my own bullet style using css.
Here is one of my css
.marker-check-mark:before{
content: "\2718";
margin: 0.5em;
color : Black;
}
this prints a "check mark" as the "ul" type.
Now i want to give its font size as 16. but i dont want this to affect the font size of the contents of this list.
Is there a way to do this.
One solution is to add font tag or span tag with syle attributes inside every li. But i want to avoid this solution.
please give me a better solution.....

If I understand what you're asking, you want to set the size of the check marks? Why not simply set the font size of the before selector?
.marker-check-mark:before {
content:"\2718";
margin: 0.5em;
color : Black;
font-size:16px;
}
FIDDLE

I think you're more-or-less answered your own question on this one!
Here's your answer:
.marker-check-mark:before{
content: "\2718";
margin: 0.5em;
color : Black;
font-size: 16px
}
The :before pseudo-element essentially acts as a stand-alone element in your DOM which means that you can style it entirely separately from the element itself. So, adding font-size to .marker-check-mark:before will not effect the font-size of .marker-check-mark.

Finding the text that has been hidden due to overflow:hidden?

I have a <div> block that contains an unknown amount of text.
The css for the block is:
.synopsis { width:600px; height:32px; line-height:16px; overflow:hidden; }
In essence the block allows for two lines of text, once the text reaches the block's limits, the rest is hidden from view.
What is the cleanest method to find out what text has been hidden from view? Any jQuery/Javascript functionality that does this?

You can remove the height from the css, or if you want to do this with jQuery you can use in something like this:
$('.synopsis').css('height','auto');

If i've understood you correctly, then a simple way to find the text that's overflowed would be to add a visible background colour and comment out the overflow:hidden on your synopsis class, something along the lines of:
.synopsis {
background: #FF0000;
height: 32px;
line-height: 16px;
/*overflow: hidden;*/
width: 600px;
}
Here a JSFiddle with what I mean: http://jsfiddle.net/UeaBA/4/

I dont think there is any easy way to obtain that in any script. The only way I can think as of now is to get the height and width of each character present in that div. You have to do certain calculations on these metrics to derive which characters fall in the visible area. This would be the most complex to do.

remove / reset inherited css from an element [duplicate]

This question already has answers here:
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.

Print sections that were hidden on the screen with javascript

I have run into a small problem I have not encountered before: I use javascript (jQuery) to show different sections of information in tabs on a web-page. So what I´m doing, is hiding the tabs that are not being viewed and only showing the tab that is being viewed.
This works very well, but now I am adding a print-specific style-sheet and I want to print the information of all tabs and not just the one being viewed.
How can I undo the javascript hiding of these sections for the print style-sheet?
Edit: Some additional information:
I am using jQuery to hide all div.tabs sections and in my print style-sheet I have set:
.wrapper div.tabs sections {
display: block;
}
assuming that the higher value of .wrapper div.tabs sections compared to div.tabs sections would make the sections visible. But it doesn´t...

The best approach would be to change the JavaScript so that it modified the classes that applied to the elements and didn't modify .style.display. Then you could target elements with those classes differently with the screen and print media stylesheets.
The quick and dirty approach would be to use !important in your print media stylesheet.

All you really need is CSS. Just define some things that show when printed.
Heres and example:
#media print {
div.print_show{ dispay: block; }
span.print_show{ display: inline; }
.print_hide{ display: none; }
}

You can add an extra class to add display:block to your print.css..

Webkit scrollbar dynamic styling

I'm currently styling the scrollbar using Webkit's ::-webkit-scrollbar CSS properties and would like to change these properties on a mousemove event. The problem is that I can't seem to find a way to get to the scrollbar's CSS dynamically.
Is it possible to style the webkit scrollbar dynamically, through javascript (possibly using jQuery)?

There is a nice workaround for this problem, you can add multiple css classes with diffident styles for the scrollbar, and then change the classes dynamically with Javascript.
Example:
.red::-webkit-scrollbar { ... }
.blue::-webkit-scrollbar { ... }
A button that toggles between the classes red and blue:
$("#changecss").on("click", function(){
$(".red,.blue").toggleClass("red").toggleClass("blue");
});
Here is a working fiddle: http://jsfiddle.net/promatik/wZwJz/18/

Yes, you can do it.
You need to include dynamically css style rule into stylesheet.
And then to change it.
You can do it by this plugin
If you don't need to use jQuery - you can do it by pure Javascript:
link 1
link 2.
But there is cross-browser problems.
Also see Setting CSS pseudo-class rules from JavaScript

If you want to change a scrollbar properties when mouse is over it. You can do it with CSS, here an example http://jsfiddle.net/olgis/7Lg2R/ (sorry for ugly colorset).
If you want to change scrollbar colour if the mouse is over a container then look at this post Style webkit scrollbar on certain state . There are described several ways of doing it, with and without JavaScript.
REMARK: I do not know for which reason none of those example (with CSS neither JavaScript) do NOT work in my Firefox 11 for Mint, but all of them works perfectly in Chrome 18.0.1025.151.

i created page with four tabs each different color set as well as scroll bar
however this only worked by giving class to body tag
body.greenbody::-webkit-scrollbar {
width: 10px;
}
body.greenbody::-webkit-scrollbar-track {
background-color:rgb(0,50,0);
}
body.greenbody::-webkit-scrollbar-thumb {
background-image:url("../assets/ScrollGreen.png");
}
/
body.bluebody::-webkit-scrollbar {
width: 10px;
}
body.bluebody::-webkit-scrollbar-track {
background-color:rgb(0,0,50);
}
body.bluebody::-webkit-scrollbar-thumb {
background-image:url("../assets/ScrollBlue.png");
}
html
<body id="body" class="greenbody" bgcolor="#202020">
javascript for each tab button(only scroll bar section shown here)
document.getElementById("body").className="greenody";
.........other function()....
document.getElementById("body").className="bluebody";
ScreenShot1 GreenScrollBar Image
ScreenShot2 BlueScrollBar Image

For this you should replace the scrollbar altogether.
It's just a matter of picking whichever one gives you the easiest API.

You can style scrollbars with CSS3, these generally only work for internal scrollbars and not the actual browser main scrollbar. You can also add the MOZ attribute to the following.
::-webkit-scrollbar {
width: 10px;
height: 10px;
}
::-webkit-scrollbar-button:start:decrement,
::-webkit-scrollbar-button:end:increment {
display: none;
}
::-webkit-scrollbar-track-piece {
background-color: #3b3b3b;
-webkit-border-radius: 6px;
}
::-webkit-scrollbar-thumb:vertical {
-webkit-border-radius: 6px;
background: #666 url(scrollbar_thumb_bg.png) no-repeat center;
}
Demo: http://geryit.com/lib/custom-css3-scrollbars
Download Source: http://geryit.com/lib/custom-css3-scrollbars/custom-css3-scrollbars.zip

you can make a <style> tag with id="scrollbar_style" and then add css inside it dynamicly like this :
document.getElementById('scrollbar_style').innerHTML = '::-webkit-scrollbar{width:15px;}';
just remember that using innerHTML on an element WILL NOT JUST ADD your new code, it WILL ALSO DELETE whatever was inside that element.
problem solved.

you can define a function in JavaScript with your own css.
function overFlow(el) {
el.style.cssText = "overflow: auto;";
}
using in html:
<style>
::-webkit-scrollbar{display = none;}
</style>
<div id="overFlow" onclick="overFlow(this);">Something</div>
