As currently the default django post create,delete and update views have been used in the application. The following changes is expected after taking over this issue: There should be three sections for any post: a)Title b) Tags c) Content Following changes are also expected:

1. Change the UI of the Create Post page as no box should be displayed just a heading for each purpose and after that space for writing the content.
2. Add option to change the font size and style while writing the post.
3. Add option to add links.
4. Add option to highlight any content.
5. Add option to add GIFS.
6. Add option to add images of custom size while writing the post.
