so you can easily decide colors, sizes, shapes, etc of default/common wordpress elements whether it be the header, footer, sidebar, post body etc.
I ask this because ID’s and classes need to be correct, WP has names for those.
I am moving this post to the WP forum.
but AFIK the answer is no.Which makes sense as the HTML and CSS for WP will VARY depending on the theme used and what alterations you have made to its PHP files, so really it it wouldn’t be sensible to have an ‘genera’ tool.
The best way is through a good CSS editor and familiarizing yourself with the output (HTML patterns, ID, classnames) of your particular theme.
