Hi all,
I would like to know some doubts that I have. I have observer that some websites are using “div” and other “tables”.
What is the difference between those 2? What do I get or what results, if I use “div” or “tables” in my website.
I would like to hear some professional opinions.
Thanks a lot to all,
