Taco HTML Edit Help > Previewing CSS/JavaScript
Taco HTML Edit supports both Preview and Live Preview for CSS and JavaScript documents. The first time that you attempt to use Preview or Live Preview on a CSS or JavaScript document, Taco HTML Edit will prompt you to select a preview file. You should select an HTML or PHP file that references the CSS/JavaScript document that you are attempting to preview. If you later want to change the preview file, you can do so in Taco HTML Edit's Get Info panel. With the CSS/JavaScript document open, select "Get Info" from the "File" menu.
