For example, I have this:

<input type='search' placeholder='Search' name='q' />

How can I style the placeholder with CSS? By default it's gray, but I'd like it to be black. Do I have to use JavaScript instead?

回答1:

no standard way, and not every browser supports place holder yet.

Something like this should do it.:

/* prefix with input if you want, but this will catch input and texatrea */
  ::-webkit-input-placeholder {  color: #000;}
  :-moz-placeholder { color: #000; }

if you want old and new browsers to support placeholder (IE6-9) there appears to be a jquery plugin(s), here is one, https://github.com/mathiasbynens/Placeholder-jQuery-Plugin however, I have not used it before.

input[placeholder="Search"]
{
color: red
}
