• Fixes [Bug] Mobile Responsiveness Issue on search-index.html Page #142 by @wendy640

Description

This PR resolves all the mobile responsiveness issues on the search-index.html page. Making it responsive all the way to the standard 320px screen width.

Technical details

This was implemented using the already existing design guidelines and implementation
-By adjusting the grid-column property, based on the screen width
-Applying the var(--vocabulary-page-edges-space) value as margin for smaller screen sizes, so the content is not directly against the screen bezels
-Reseting styles that break the content arrangement on smaller screens.

This approach also put into consideration other context pages, making changes that would contribute towards resolving mobile responsiveness issues on other context pages.

Tests

• Fork and the clone the creativecommons/vocabulary project unto your local machine.
• Launch the search-index.html file on your browser
• Toggle the developer console by hitting Ctrl + shift + I and then toggling the option for device toolbar.
• Test the UI at all screen sizes for mobile responsiveness by visual inspection of each element. Particularly screen sizes lesser than 680px
• Test the UI on various browsers for compatibility.

Hello @possumbilities

Going over the list of issues in the repo, I see a lot of responsiveness issues. By inspection, a lot of them are related and can be resolved by similar style changes. Hence, could this PR for a foundation for the resolution of all the mobile responsiveness issues for all the contexts in the vocabulary docs. Is this a good idea, or that would just be too many changes for one PR?
