HTML5 tags: What are they and what are their functions?

What is an HTML5 tag?

First of all, let’s see what an HTML5 tag is.

HTML5 tags work as part of a code that fulfils a simple function. This function is based on helping browsers understand the content contained in each of the tags used.

In addition, it is important to highlight that each label has different attributes that determine how each one works. They all begin with the symbol “<” and end with the opposite symbol, “>”. The name corresponding to the label must be included between these symbols so that the browser can assimilate it properly.

It is also important to know that HTML5 tags are made up of an opening and a closing tags. However, there are tags that do not have the closing version like those used to upload images. Closing tags use the “/” symbol before the tag name.
