Hi all

I am new to the forum, i have experience in HTML, PHP and some other languages, still try much a beginner. I am looking for some code that will allow me to have an illustration box on one side (with a 3D box) and the dimensions on of the box on the other, i would like the dimensions to be editable and for the illustration to change size when a particular value is changed, very much like the one on the bellow link:


Any ideas where to start

(very sorry if tho post is in the completely wrong section)
