[html] Remove scrollbar from iframe

Using this code

<iframe frameborder="0" style="height: 185px; overflow:scroll; width: 100%" src="http://www.cbox.ws/box/?boxid=439&boxtag=7868&sec=main" marginheight="1" marginwidth="1" name="cboxmain" id="cboxmain" seamless="seamless" scrolling="no" frameborder="0" allowtransparency="true"></iframe>

This is how it appears (the shoutbox on homepage of http://www.talkjesus.com)

How do I remove the horizontal scrollbar and modify the css of the vertical scrollbar?

If anyone here is having a problem with disabling scrollbars on the iframe, it could be because the iframe's content has scrollbars on elements below the html element!

Some layouts set html and body to 100% height, and use a #wrapper div with overflow: auto; (or scroll), thereby moving the scrolling to the #wrapper element.

In such a case, nothing you do will prevent the scrollbars from showing up except editing the other page's content.

This is a last resort, but worth mentioning - you can use the ::-webkit-scrollbar pseudo-element on the iframe's parent to get rid of those famous 90's scroll bars.

::-webkit-scrollbar {
    width: 0px;
    height: 0px;
}

Edit: though it's relatively supported, ::-webkit-scrollbar may not suit all browsers. use with caution :)

Adding scroll="no" and style="overflow:hidden" on iframe didn't work, I had to add style="overflow:hidden" on body of html document loaded inside iframe.

Add this in your css to hide just the horizontal scroll bar

iframe{
    overflow-x:hidden;
}

Try adding scrolling="no" attribute like below:

<iframe frameborder="0" scrolling="no" style="height:380px;width:6000px;border:none;" src='https://yoururl'></iframe>

Add scrolling="no" attribute to the iframe.

<div id="myInfoDiv" seamless="seamless" scrolling="no" style="width:100%; height: 100%; float: left; color: #FFF; background:#ed8719; line-height:100%; font-size:100%; font-family: sans-serif>;

Use the above div and it will not show scroll bar in any browser.

Just Add scrolling="no" and seamless="seamless" attributes to iframe tag. like this:-

 1. XHTML => scrolling="no"
 2. HTML5 => seamless="seamless"

UPDATE:

seamless attribute has been removed in all major browsers

This works in all browsers. jsfiddle here http://jsfiddle.net/zvhysct7/1/

<iframe src="http://buythecity.com"  scrolling="no" style=" width: 550px; height: 500px;  overflow: hidden;" ></iframe>

Add this in your css to hide both scroll bar

iframe 
{
  overflow-x:hidden;
  overflow-Y:hidden;
}

iframe {
  display: block;
  border: none;         /* Reset default border */
  height: 100vh;        /* Viewport-relative units */
  width: calc(100% + 17px);
}
div {
  overflow-x: hidden;
}

Like this you make the width of the Iframe larger than it should be. Then you hide the horizontal scrollbar with overflow-x: hidden.
