Step-by-step explanation:
HTML is an acronym for hypertext markup language and it is a standard programming language which is used for designing, developing and creating web pages.
Generally, all HTML documents are divided into two (2) main parts; body and head. The head contains information such as version of HTML, title of a page, metadata, link to custom favicons and CSS etc. The body of the HTML document contains the contents or informations that a web page displays.
In the design phase of a website design, the website designer create a mock-up aimed at the target user. A mock-up is a graphical representation or illustration of a graphic design and as such isn't responsive.
