In order to spice up the ads I'm publishing on this classified site, I inject my own CSS within <style>...</style> tags. To do so, I use the HTML tab provided on the Textarea of the form (like eBay). These tags are therefore within the BODY of the whole document (I obviously have no access to the <head> section of it).
It works fine but I'm wondering if forcing <style>...</style> in the BODY itself is Ok from a technical stand point. I'm worried about disrupting the good functionning of the site.
Thanks for any input or other ideas for doing the same thing, but please, don't suggest inline styling.
