Answer:
Split view.
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 of a web page to be displayed.
Split view allows the user to see the source code and the visual representation simultaneously.
It can be used in graphic design software such as Adobe Dreamweaver to get a side-by-side view of both the source code and code layout modules or design and source code.
For example, a user with a dual screen monitor can use the split view feature to display the design on monitor while using the other to display the source code.
