We want to have a modal popup form on clicking a image or link. Though i achieved this on CMS page using template page(.phtml), I want to use this form on every page, so i am using a static block inside header.phtml.
Now the problem is style tags of the static block is overriding the default CSS, hence the page is getting distort. Please help me with a way, so that the static block CSS doesn't effect other part of the pages.
