To use display:none
is a good option just to removing an element BUT it will be also removed for screenreaders. There are also discussions if it effects SEO. There's a good, short article on that topic on A List Apart
If you really just want hide and not remove an element, better use:
div {
position: absolute;
left: -999em;
}
Like this it can be also read by screen readers.
The only disadvantage of this method is, that this DIV is actually rendered and it might effect the performance, especially on mobile phones.
