Oh, crap. Problems with Internet Explorer

Firefox is not OK, but maybe it will be if you validate the site.

How do you validate the site?

He means this: https://validator.w3.org/check?uri=https://www.onlyidol.com/blog&charset=(detect+automatically)&doctype=Inline

Or go here: https://validator.w3.org/ Add your blog’s url address and check it.. You can check the css file out as well as just the site or blog itself… =)

So, how do I fix it once tells me what’s missing in this case?

You alter your original files to valid what’s not validated, then you recheck again, and again, until you have no errors.
