HTML5 iFrame Seamless Attribute

Question

in HTML5 the iframe has new attributes like \'seamless\' that should remove borders and scrollbars. I\'ve tried it but doesn\'t seem to work, I still can see scrollbars and

Answer 1

I thought this might be useful to someone:

in chrome version 32, a 2-pixels border automatically appears around iframes without the seamless attribute. It can be easily removed by adding this CSS rule:

iframe:not([seamless]) { border:none; }

Chrome uses the same selector with these default user-agent styles:

iframe:not([seamless]) {
  border: 2px inset;
  border-image-source: initial;
  border-image-slice: initial;
  border-image-width: initial;
  border-image-outset: initial;
  border-image-repeat: initial;
}
