Make Suggestion Style Properties in UI_dashboard

Describe the bug
We also need some suggestion on the input box for size properties like border radius, width, font-size, height etc. All this properties only need some pixels, em, %, vh or vw
We can always make some meaningful global suggestions for the users. example (9px, 100%, 100vh, 20px, etc)

File/Files you will work on
ui_dashboard.html

Possible Lines of Code
You should not add above the possible lines of code. (if given)

Result or Final Looks
At the end of the day, your code should make it easier for people. When people click a size property(example: height, border radius, width etc), they should get some really good suggestions. HINT=Use HTML datalist tag, Get more information from the dashboard.html file as many people have made similar contributions to values e.g(float, display etc)

Start in ui_dashboard.html and review the existing value suggestions referenced from dashboard.html, especially entries for properties such as float and display. Add datalist-based suggestions for size properties including width, height, border radius, and font-size, using useful px, em, %, vh, and vw values. Done means clicking each relevant property exposes helpful size suggestions.
