问题:

i've been trying to change the background image of the input button through css, but it doesn't work.

search.html:

<body>
    <form name="myform" class="wrapper">
        <input type="text" name="q" onkeyup="showUser()" />
        <input type="button" name="button" value="Search" onclick="showUser()" class="button"/>
         <p>
             <div id="txtHint"></div>
         </p>
    </form>
</body>

search.css:

.button {
    background-image: url ('/image/btn.png') no-repeat;
    cursor:pointer;
}

what could be wrong?

even inline-ing the css didn't seem to work.

回答1:

You need to type it without the word image.

background: url('/image/btn.png') no-repeat;

Tested both ways and this one works.

Example:

<html>
    <head>
        <style type="text/css">
            .button{
                background: url(/image/btn.png) no-repeat;
                cursor:pointer;
                border: none;
            }
        </style>
    </head>
    <body>
        <input type="button" name="button" value="Search" onclick="showUser()" class="button"/>
        <input type="image" name="button" value="Search" onclick="showUser()" class="button"/>
        <input type="submit" name="button" value="Search" onclick="showUser()" class="button"/>
    </body>
</html>


回答2:

Just to add to the answers, I think the specific reason in this case, in addition to the misplaced no-repeat, is the space between url and (:

background-image: url ('/image/btn.png') no-repeat; /* Won't work */
background-image: url('/image/btn.png'); /* Should work */


回答3:

background-image takes an url as a value. Use either

background-image: url ('/image/btn.png');

or

background: url ('/image/btn.png') no-repeat;

which is a shorthand for

background-image: url ('/image/btn.png');
background-repeat: no-repeat;

Also, you might want to look at the button HTML element for fancy submit buttons.



回答4:

If this is a submit button, use <input type="image" src="..." ... />.

If you want to specify the image with CSS, you'll have to use type="submit".
