I would like to make a html layout for my website, but i don’t how? Can anyone please explain?
That depends whether you are making a layout for a system like wordpress or joomla.
Considering you are making the website from scratch, you would generally start with an idea drawn on paper and then try to design it on programs like Photoshop.
In my opinion this is not the right way to start if you never did anything like such. You should start by downloading pre-made layouts and check how they managed to create them.
