[javascript] Remove Style on Element

I was wondering if this is possible.

There's this element

<div id="sample_id" style="width:100px; height:100px; color:red;">

So I want to remove width:100px; and height:100px;

the result would be

<div id="sample_id" style="color:red;">

Any help would be apprreciated. :)

$("#sample_id").css({ 'width' : '', 'height' : '' });

var element = document.getElementById('sample_id');
element.style.removeProperty("width");
element.style.removeProperty("height");

Just use like this

 $("#sample_id").css("width", "");
 $("#sample_id").css("height", "");

Specifying auto on width and height elements is the same as removing them, technically. Using vanilla Javascript:

images[i].style.height = "auto";
images[i].style.width = "auto";

Use javascript

But it depends on what you are trying to do. If you just want to change the height and width, I suggest this:

{
document.getElementById('sample_id').style.height = '150px';
document.getElementById('sample_id').style.width = '150px';


}

TO totally remove it, remove the style, and then re-set the color:

getElementById('sample_id').removeAttribute("style");
document.getElementById('sample_id').style.color = 'red';

Of course, no the only question that remains is on which event you want this to happen.

Update: For a better approach, please refer to Blackus's answer in the same thread.

If you are not averse to using JavaScript and Regex, you can use the below solution to find all width and height properties in the style attribute and replace them with nothing.

//Get the value of style attribute based on element's Id
var originalStyle = document.getElementById('sample_id').getAttribute('style'); 

var regex = new RegExp(/(width:|height:).+?(;[\s]?|$)/g);
//Replace matches with null
var modStyle = originalStyle.replace(regex, ""); 

//Set the modified style value to element using it's Id
document.getElementById('sample_id').setAttribute('style', modStyle);
