- HTML tags are vital components of any web page and in order to display valid content, we must utilize the up-to-date HTML5 elements.
- Since the start of HTML creation, the developer community created many HTML elements but most of them failed to keep up with the pace of new technology or they were unable to fulfill the desired outcomes.
