clean up styles and remove extra classes and html

@EnlightenedCode 
Some comments
- Filter has been updated to the collapsible panel because of responsive issues, still the content needs to be replaced right?
- ~~Freeform fields need labels as the placeholders will disappear once there's content. I cain add this change.~~ DONE
- Timeline box is not working (click to edit)
- There's an issue with the iframe, I have added a position class to avoid that gray area but the common header disappears. Can we fix that?
- Dates are showing different formats
