Styling a CSS item depending on it's value

问题:

I have a list of percentages that range from 0% through to 200%.

Is there a way to style those numbers depending on their value i.e. make numbers 0% - 100% be green and numbers 101% > red?

Please note, I don't have access to the HTML for this, just CSS.

Thanks in advance,

Tom Perkins

Edit:

The HTML in question reads:

    <td class="HtmlGridCell" colspan="5" align="Left"> </td>
    <td class="HtmlGridCell" colspan="2" align="Left"><span class="progress" title="303%"><span class="indicator warning" style="width: 100%;"> </span></span></td>

And the CSS reads:

@-moz-document url("https://customstudio.workflowmax.com/job/joblist.aspx") {
.progress:after {
content: attr(title);
font-size: 14px;
position: relative;
left: 122px;
top: -27px;
float: left;
color: #666;
background-color: #efefef;
-moz-border-radius: 4px;
padding: 5px;
border: 1px solid #cfcfcf;
font-family: "Helvetica Neue", Arial, Helvetica, Geneva, sans-serif;
}

Hope that helps.

If you could set the percentages <100% to start with a 0 like 099% , You could use the attr starts with, and attr equals selector. Works in modern browsers and ie 7 +

 .progress[title^=1], .progress[title^=2] { background: red; } /* Starts with 1 or 2*/
 .progress[title^=0], .progress[title=100%], { background: green; } /* Starts with 0 or is 100% */

Alternatively you could make a selector for all 200 odd variations you have , which is quite long winded

Since, there is evaluation of values involved, It can not be done with CSS.

But, Javascript may do what you are looking for.

回答3:

I am also not convinced that there is no possibility by using only CSS at the moment...I would suggest defining two CSS classes "green" and "red" (or corresponding) and making a small evaluation in JavaScript or PHP to assign the classes to the elements...

Sorry, but this needs access to HTML in any kind.

This really depends on the kind and structure of HTML elements you'd want to select. If you have only <span> or <td> elements without any kind of semantic structure it won't work.

But if you happen to have attributes like title, class, etc you could do sth. like this:

span[attributeName="attributeValue"] {color: #FF0000}
