As far as I can tell there is no other way than to override all properties. The styles are defined on the element, they won&#39;t just disappear because of another selector that targets the element.

If you only want to remove the pseudo element from the page you can do `content: none`.

***Added from comments below:***

&gt;The difference between content: &quot;&quot; and content: none is that content: &quot;&quot; produces a pseudo-element with no content (i.e. an empty pseudo-element), whereas content: none prevents the pseudo-element from being generated at all.

Here `content: &quot;&quot;;` doesn&#39;t affect at all if you want to remove that pseudo you have to use `content:none;` it will remove previously added pseudo content. 

    content:none;

If that doesn&#39;t help you can also try : 

    display:none; 

if still, it doesn&#39;t work then you could try the below, but I **never** suggest you use **!important**

     display:none !important;

here is working jsfiddle

In the regex below, `\s` denotes a space character.  I imagine the regex parser, is going through the string and sees `\` and knows that the next character is special.

But this is not the case as double escapes are required.

Why is this?

    var res = new RegExp(&#39;(\\s|^)&#39; + foo).test(moo);

Is there a concrete example of how a single escape could be mis-interpreted as something else?

Why do regex constructors need to be double escaped?

I know that has been asked before, but I find no clean way of overriding this CSS:

&lt;!-- language: lang-css --&gt;

    .ui-input-search:after {
        content: &quot;&quot;;
        height: 18px;
        left: 0.3125em;
        margin-top: -9px;
        opacity: 0.5;
        position: absolute;
        top: 50%;
        width: 18px;
    }

I need to leave `ui-input-search` on the element, but can add my own class, like:

&lt;!-- language: lang-css --&gt;

    .ui-input-search-no-pseudo:after {
       content: &quot;&quot;;
    }

**Question**:  
Is there an easy way to remove &quot;pseudo-css&quot; without having to overwrite the CSS line by line?

Thanks!

How do I override CSS set on a pseudo element?

I&#39;d like to make one of the FontAwesome icons a bit less heavy - it&#39;s much heavier than the font I am using. This how it looks presently:

![heavy remove icon, next to lightweight font][1]: 

Ugly, right? So I&#39;ve tried resetting the font-weight as follows: 

    .tag .icon-remove  { 
      font-weight: 100;
    }

The attribute appears to be set correctly in the CSS, but it has no effect - the icon looks just as heavy as before. I&#39;ve also tried `font-weight: lighter` and `-webkit-text-stroke-width: 1px` with no effect. 

Is there any way I can make the icon less heavy? The docs say &quot;[Anything you can do with CSS font styles, you can do with Font Awesome][2]&quot; but I can&#39;t figure out how to do this.

I&#39;m trying to style the sections inside the AutoComplete, but I don&#39;t know what to put in the CSS *for* the sections. I&#39;m specifically trying to make:

    border-radius: 0px;
    border: 1px solid #454545;


Any suggestions???

Styling JQuery UI Autocomplete

I was reading https://stackoverflow.com/questions/13854198/can-you-make-an-iframe-responsive, and one of the comments/answers led me to [this JSFiddle.][2]

But when I tried to implement the HTML and CSS to fit my needs, I didn&#39;t have the same results/success. I created [my own JSFiddle][3] so I could show you how it doesn&#39;t work the same for me. I&#39;m sure it has something to do with the type of iFrame I&#39;m using (e.g., the product images might need to be responsive too or something?)

My main concern is that when my blog readers visit my blog on their iPhone, I don&#39;t want everything to be at x width (100% for all my content) and then the iFrame misbehaves and is the only element wider (and hence sticks out past all the other content - if that makes sense?)

Does anyone know why it&#39;s not working?

Here is the HTML &amp; CSS of my JSFiddle (if you don&#39;t want to click on the link):

    

&lt;!-- begin snippet: js hide: false console: true babel: false --&gt;

&lt;!-- language: lang-css --&gt;

    .wrapper {
      width: 100%;

      margin: 0 auto;

    .h_iframe {

    }

    .h_iframe .ratio {
      display: block;
      width: 100%;

    }

      position: absolute;
      top: 0;
      left: 0;
      width: 100%;

    }

&lt;!-- language: lang-html --&gt;

    &lt;div class=&quot;wrapper&quot;&gt;
      &lt;div class=&quot;h_iframe&quot;&gt;

Making an iframe responsive

I wrote some example to see what is the difference, but they display me same results for width and height.

    &lt;html&gt;
        &lt;head&gt;
            &lt;script type=&quot;text/javascript&quot; src=&quot;jquery.js&quot;&gt;&lt;/script&gt;
            &lt;script type=&quot;text/javascript&quot;&gt;
                $(document).ready(function(){
                    var div = $(&#39;.test&#39;);
                    var width = div.width(); // 200 px
                    var innerWidth = div.innerWidth(); // 200px
                    var outerWidth = div.outerWidth(); // 200px
                    
                    var height = div.height(); // 150 px
                    var innerHeight = div.innerHeight(); // 150 px
                    var outerHeight = div.outerHeight(); // 150 px
                });
                
            &lt;/script&gt;
            &lt;style type=&quot;text/css&quot;&gt;
                .test
                {
                    width: 200px;
                    height: 150px;
                    background: black;
                }
            &lt;/style&gt;
        &lt;/head&gt;
        &lt;body&gt;
            &lt;div class=&quot;test&quot;&gt;&lt;/div&gt;
        &lt;/body&gt;
    &lt;/html&gt;

In this example you can see that they output same results. If anyone know what is the difference please show me appropriate answer.

Thanks.

Does the override identifier after virtual destructor declaration have any special meaning?

&lt;!-- language: cpp --&gt;
    
    class Base
    {
    public:
        virtual ~Base()
        {}
        
        virtual int Method() const
        {}
    };
    
    class Derived : public Base
    {
    public:
        virtual ~Derived() override
        {}
        
        virtual int Method() override // error: marked override, but does not override - missing const
        {}
    };
    
Using override identifier on virtual method is useful as check: compiler will report error when the Base virtual method is actualy not overriden.

Does override on virtual destructor has any meaning/function too?

Is it possible to override `onBackPressed()` for only one activity ? 

On back button click I want to call a dialog on a specific Activity, but in all other activities i want it to work as it worked before (going to previous activities).

**EDITED**

Thank you everyone for your answers, I already had everything like you told me, but my problem was that when i was clicking back button on another Activity, I was going to my previous Activity (The one where i had back button Overridden) and i thought that it wasn&#39;t working, i thought it was overriding `onBackPressed()` in whole Application, now i got it.

I would like to use `::before` to place SVG images before some selected elements:

```css
#mydiv::before {
  content: &#39;&lt;svg ... code here&lt;/svg&gt;&#39;;
  display: block;
  width: 22px;
  height: 10px;
  margin: 10px 5px 0 10px;
}
```
Above code just displays the plaintext.  
I checked the spec and there seem to be some restrictions on what `content` can be. CSS `content` property solution is preferable.



Is there a way to use SVG as content in a pseudo element ::before or ::after

I&#39;m trying to make a search bar that will look nice. What I did is, I made an image of an search bar and I&#39;m adding the image to the back-ground of the input and I&#39;m editing the place and the size that the font will appear.
The only thing that I can&#39;t find a way to edit is the small &#39;x&#39; button that appears when I&#39;m using input type search.
I want to move it a little bit left so it will fix my search bar image.

Here is my HTML:

    &lt;input id=&quot;search&quot; name=&quot;Search&quot; type=&quot;search&quot; value=&quot;Search&quot; /&gt;

Here is my CSS:

    #search{
        width: 480px;
        height: 49px;
        border: 3px solid black;
        padding: 1px 0 0 48px;
        font-size: 22px;
        color: blue;
        background-image: url(&#39;images/search.jpg&#39;);
        background-repeat: no-repeat;
        background-position: center;
        outline: 0;
    }

Editing input type=&quot;search&quot; Pseudo-element Button (&#39;x&#39;)

[Here](http://jsfiddle.net/C7rSa/) is a fiddle.

    &lt;p&gt;foo &lt;a class=&quot;infolink&quot; href=&quot;#&quot;&gt;bar&lt;/a&gt; baz&lt;/p&gt;

and

    a.infolink::before
    {
        content: &#39;?&#39;;
        background: blue;
        color: white;
        width: 20ex;
        height: 20ex;
    }

The &#39;?&#39; appears but clearly does not have 20ex size. Why not? Tested in Firefox and Chrome.

Does the `select` tag allows to use the `:after` selector in order to create a pseudo element after it? 

I&#39;ve tried on Chrome, Safari and Firefox on Mac and it doesn&#39;t seem to work.

Pseudo elements and SELECT tag

I have a SVG graphic put like this:

    a::before { content: url(filename.svg); }

When I hover over the &lt;a&gt; tag, I really want the SVG to change the fill color, without loading a new SVG file, as I have now:

    a:hover::before { content: url(filename_white.svg); }

Is this possible to achieve using JavaScript, jQuery or just pure CSS that I am not aware of?

Thanks.
