    left:auto;

This will default the `left` back to the browser default.


----------


So if you have your Markup/CSS as:

    &lt;div class=&quot;myClass&quot;&gt;&lt;/div&gt;

    .myClass
    {
      position:absolute;
      left:0;
    }

When setting RTL, you could change to:

    &lt;div class=&quot;myClass rtl&quot;&gt;&lt;/div&gt;

    .myClass
    {
      position:absolute;
      left:0;
    }
    .myClass.rtl
    {
      left:auto;
      right:0;
    }

In the future one would use `left: unset;` for unsetting the value of left.

As of today 4 nov 2014 `unset` is only supported in Firefox.

[Read more about unset in MDN.][1]

My guess is we&#39;ll be able to use it around year 2022 when IE 11 is properly phased out.

    left: initial

This will also set `left` back to the browser default.


But important to know `property: initial` is not supported in IE.


I&#39;m very new to C and I have this code: 

    #include &lt;stdio.h&gt;
    #include &lt;math.h&gt;
    int main(void)
    {
      double x = 0.5;
      double result = sqrt(x);
      printf(&quot;The square root of %lf is %lf\n&quot;, x, result);
      return 0;
    }

But when I compile this with:

    gcc test.c -o test

I get an error like this:

    /tmp/cc58XvyX.o: In function `main&#39;:
    test.c:(.text+0x2f): undefined reference to `sqrt&#39;
    collect2: ld returned 1 exit status


Why does this happen? Is `sqrt()` not in the `math.h` header file? I get the same error with `cosh` and other trigonometric functions. Why?


Why am I getting &quot;undefined reference to sqrt&quot; error even though I include math.h header?

I have an activity with a listview. When the user click the item, the item &quot;viewer&quot; opens:

    List1.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1, int arg2,long arg3) {

            Intent nextScreen = new Intent(context,ServicesViewActivity.class);
            String[] Service = (String[])List1.getItemAtPosition(arg2);

            //Sending data to another Activity
            nextScreen.putExtra(&quot;data&quot;, datainfo);
            startActivityForResult(nextScreen,0);
            overridePendingTransition(R.anim.right_enter, R.anim.left_exit);
        }
    });

This works fine, but on the actionbar the back arrow next to the app icon doesn&#39;t get activated. Am I missing something?


How to implement the Android ActionBar back button?

I&#39;m overriding the site CSS to an RTL version when specific language is chosen.

I have an element which has to have absolute positioning. In the LTR version, I do `left: 0px;` and it&#39;s aligned to the left; in the RTL version I want to do the opposite with `right`, but the `left` property isn&#39;t overridden so it still stays to the left.

 - I&#39;ve tried hacking with `!important`, but that didn&#39;t work.
 - I&#39;ve tried setting `left: none`, but that didn&#39;t work.

How can I either set it to none or remove it completely while overriding?

How to remove Left property when position: absolute?

Is it possible to use CSS transitions to animate something between a position set as `left: 0px` to `right: 0px` so it goes all the way across the screen? I need to accomplish the same thing with top to bottom. Am I stuck calculating the screen width / object-size?

&lt;!-- language: lang-css --&gt;

    #nav {
        position: absolute;
        top: 0px;
        left: 0px;
        width: 50px;
        height: 50px;
        -webkit-transition: all 0.5s ease-out;
    }
    
    .moveto {
        top: 0px;
        right: 0px;
    }

and then I use jQuery&#39;s `.addClass`

CSS transition between left -&gt; right and top -&gt; bottom positions

I think this is not possible, but I thought I ask in case there is a way. The idea is that I have a variable for path to web resource folder:

    @root: &quot;../img/&quot;;
    @file: &quot;test.css&quot;;
    @url: @root@file;

    .px {
        background-image: url(@url);
    }

I get this as a result:

    .px { background-image: url(&quot;../img/&quot; &quot;test.css&quot;); }

But, I want the strings to combine into one string like this:

    .px { background-image: url(&quot;../img/test.css&quot;); }

Is it possible to concatenate strings together in Less?

How can I align two inline-blocks so that one is left and the other is right on the same line? Why is this so hard? Is there something like LaTeX&#39;s \hfill that can consume the space between them to achieve this?

**I don&#39;t want to use floats** because with inline-blocks I can line up the baselines. And when the window is too small for both of them, with inline-blocks I can just change the text-align to center and they will be centered one atop another. Relative(parent) + Absolute(element) positioning has the same problems as floats do.

The HTML5:

    &lt;header&gt;
        &lt;h1&gt;Title&lt;/h1&gt;
        &lt;nav&gt;
            &lt;a&gt;A Link&lt;/a&gt;
            &lt;a&gt;Another Link&lt;/a&gt;
            &lt;a&gt;A Third Link&lt;/a&gt;
        &lt;/nav&gt;
    &lt;/header&gt;

The css:

    header {
        //text-align: center; // will set in js when the nav overflows (i think)
    }
    
    h1 {
        display: inline-block;
        margin-top: 0.321em;
    }
    
    nav {
        display: inline-block;
        vertical-align: baseline;
    }

Thery&#39;re right next to each other, but I want the `nav` on the right.

Align two inline-blocks left and right on same line

I have a link button inside a `&lt;td&gt;` which I have to disable. This works on IE but not working in Firefox and Chrome.
Structure is - Link inside a `&lt;td&gt;`. I cannot add any container in the `&lt;td&gt;` (like div/span)

I tried all the following but not working on Firefox (using 1.4.2 js):


  

    $(td).children().each(function () {
            $(this).attr(&#39;disabled&#39;, &#39;disabled&#39;);
      });
    
    
      $(td).children().attr(&#39;disabled&#39;, &#39;disabled&#39;);
    
      $(td).children().attr(&#39;disabled&#39;, true);
    
      $(td).children().attr(&#39;disabled&#39;, &#39;true&#39;);

Note - I cannot de-register the click function for the anchor tag as it is registered dynamically. AND I HAVE TO SHOW THE LINK IN DISABLED MODE.

What Does &#39;zoom&#39; do in CSS?

I&#39;m trying to position a Bootstrap popover for a trigger that sits on the far top-right corner of a 960px wide web page.

Ideally, I&#39;d position it on the bottom and move the arrow with CSS (so the arrow is on the top-right of the popover). Unfortunately the &#39;placement&#39;:&#39;bottom&#39; positioning is not enough, since it will center it below the trigger.

I&#39;m looking for solution that will place the popover statically below and on the left of the trigger.

There are any shorthand for `top` `right` `bottom` `left` or for `width` and `height` ?

I have a lot of css like this

    #topDiv {
    	position:absolute;
    	top:0px;
    	left:0px;
    	right:0px;
    	height:100px;
    }
    #centerDiv {
    	position:absolute;
    	top:100px;
    	bottom:120px;
    	left:0px;
    	right:0px;
    }
    #consoleDiv {
    	position:absolute;
    	left:0px;
    	right:0px;
    	bottom:0px;
    	height:120px;
    }

I would like to do anything like this

    position: absolute 10px 50px 50px 100px;


or

    size: 400px 200px; 

CSS shorthand for positioning

I want to position four `div`s relative to another.  I have a rectangle `div`, and I want to insert 4 `div`s at its corners.  I know that CSS has an attribute `&quot;position:relative&quot;`, but this is relative to the normal position of that element.  I want to position my `div`s not relative to their normal position, but relative to another element (the rectangle). What should I do?

Position one element relative to another in CSS

`.offset([coordinates])` method set the coordinates of an element but only relative to the document. Then how can I set coordinates of an element but relative to the parent?

I found that `.position()` method get only &quot;top,left&quot; values relative to the parent, but it doesn&#39;t set any values.

I tried with 

    $(&quot;#mydiv&quot;).css({top: 200, left: 200});

but does not work.

In jQuery how can I set &quot;top,left&quot; properties of an element with position values relative to the parent and not the document?

i have a fixed header with 100% width.

    #header {
    background: #2e2e2e;
    width: 100%;
    z-index: 999;
    position: fixed;
    }

browsers scrollbar is under my fixed div. How to fix that?
