If you don't know HTML (at least the basics) you won't stand a chance unless you go back to the HTML program and redo the whole page again.
Learning just even the basics will save you a lot of time and money paying for an expert to locate the source of the trouble and correct/change information for you.
As a complete HTML beginner, most people are very confused when trying to learn html and trying to sift through all the technical jargon that comes with it. Learners soon become disheartened and give up. My book is for absolute beginners with just the very basics of html to get started and very easy to understand and implement. No technical jargon as to the how's and why's, and you will quickly gain your confidence!
