stylesheet

问题 I need a function to change the appearance of some elements in my HTML page "on the fly", but I am not able to do it. The problem is that I cannot use a command like document.write ('<style type="text/css">body {background-color: #cccccc;}</style>'); because I need to make the changes effective when the page is already loaded, using a link like <a onmouseclick="Clicker(1)" href="#">clic</a> and I cannot use a command like document.body.style.background = '#cccccc'; because I do not know if it

问题 How would I go about adding a dynamic ".........." to a restaurant menu in CSS? Like in printed ones they have the whole "our food is made of blah blah blah.............$24.99." How would you do that in CSS? Or is this even possible? 回答1: The best solution is this: <ul> <li><p class="food">Chinese Food</p><p class="price">$5.99</p></li> </ul> then CSS to match (untested, but tweakable to get the effect) li { width: 300px; height: 20px; border-bottom: 1px dotted black; background-color: white;

问题 I'm in London working on an application, and the html/css guy is in New York. He's sending me updates daily by email as we have no source control set up that we can both use, I'm constantly making small changes to his css, so each time I get a new file from him, I have to reapply all my changes to it, and obviously the more work I do, the longer this takes each time.
