Remove ExtJS Styling

I need to remove styling fron HTML I insert into a fieldset/panel. I recall reading somewhere (in one of the newer releases) that ExtJS provides this features, but I need it for an older release. Has anybody implemented this capability/feature - specifically for ExtJS - or have a suggestion that will work for 开发者_开发问答ExtJS? Thanks.

You mean you want to override the default inherited styles like the reset CSS that is applied globally? There's nothing built-in for that -- you basically have to write whatever override CSS you need and apply it after the Ext stylesheets. Make sure that you give your parent panel an id or cls, then write your override rules to be relative to that id/cls. I know it's a bit of a pain, but that's what you have to do.
