Hello

i have a page with approx. 60 headers, all with the same style (h2) and 60 images. is it possible to change all 60 headers at once to h1 and maybe later to another style and all 60 images at once to create a blue blur?? maybe with a class or something?

it is a simple product page , with title - image - weight...

should be better if it can be changed all at once..
