In all the previous examples we discussed, we have done the complete View coding in a single file. This will result in a lack of flexibility and reduced reusability.
Consider the following web page structure where the Top Section contains the company logo or banner and the Side Section contains the links to various sections of the site. The Content Section changes for every page.
If we code the complete content in a single view, we may have to duplicate the Top Section and Side Section in every page. If we want to change anything in the Side Section, we will have to change all the files. This clearly shows that a single View file is not the best solution.
The layout comes to the rescue in this scenario. The layout defines the site structure that can be reused across all the web pages. The layout does not even need to have something like the top section or side section; it can contain even a simple HTML structure where you can have common content and the body content will be rendered...
