CSS Script

Inline css script runner. Use javascript to define css value or eval script directly via css. CSS Script is DOMList and jQuery extension. To makes CSS Script working, you should load it after loading DOMList. If you want to use jQUery, then you must load jQPatch before load this.


cssproperty: '%(SCRIPT)%';

Scripts should be inside %()% pattern. Currently we have param $i as index number of selected element.


By default, CSScript convert the CSSRule string to CSSRule object if contains CSScript pattern. If you want to convert all rules no matter they have CSScript pattern or not, please write config before loading the CSScript.

WARNING! Converting all rules will takes load time on a big css.

We also added AutoRender support for DOM insertion event. So, when some dom element inserted into document, CSSCript will re-render. We use animation to define insertion event since dom mutation event already deprecated. By default we turn this feature off for performance support. You can enable it by adding configs before loading CSScript.

  • window.CSScriptExtractAll - Extract all rules.
  • window.CSScriptAutoRender - Re-render styles when DOM element inserted into document.
Config sample
    <script type="text/javascript">
        // Extract all rules.
        window.CSScriptExtractAll = true;
        // Enable auto-render on DOM insertion.
        window.CSScriptAutoRender = true;
    <script type="text/javascript" src="csscript/dist/csscript.min.j"></script> 

If you want to access the converted rules, you can read window.CSScriptLists object in browser console.


You can get CSScript by choosing download above or using:

npm install csscript


bower install csscript

@media only screen and (max-width: 1024) {
    .fit-list {
        script: '%( $(this).appendTo(".container-content") )%';

Manual Render

Use $.renderCSScript() to re-render the styles. Usually, it's usefull when you want to use CSScript after loading ajax or drawing new element.

$.ajax('http://localhost').complete(function(data) {
    // Re-render styles after ajax complete and inserting content complete.
