Html titles

This tags are fundamental for the structure and comprehension of your webpage.The format of the title tag is <h1></h1>,<h2></h2>...And so on until the <h6></h6> tag, which will be the smallest heading.<h1></h1>should be the most important title on your page, because it will appear as a big, bold text.So imagine you have a web that sells computers, the <h1></h1> should be something like "Computer sales".And a <h2></h2> title could be "Second hand computers".
