How do I make an element appear with javascript without overriding style? -


i have following code display div hidden:

document.getelementbyid('thediv').style.display = 'block';

the problem when execute this, div loses prior css formatting. there way can have same functionality while keeping css formatting?

setting style.display block has no effect on other css formatting. 1 exception can think of if item display:inline, setting display:block change layout. but, other css items unaffected.

if not observing, may not telling whole story here , else aren't showing code must going on. if that's case, please try reduce test case small example in jsfiddle can see actual code causes problem.
