Thanks! Visually, the edit icon looks bigger than the link icon. Can we make them match better?

[Pratik2026]

@alya, I have resized the icon. Let me know if further adjustments are required.

[alya]

Thanks! Please update the icon in the help center as well:

% git grep "pencil and" help/                  
help/include/manage-this-user-via-user-profile.md:1. Select the **Manage user** tab, or click the **pencil and paper**
help/include/manage-user-tab-tip.md:    You can also access the **Manage user** tab by clicking the **pencil and
help/preview-your-message-before-sending.md:Click the **pencil and paper** (<i class="fa fa-edit"></i>) icon to resume editing.

Are you up for adding a help center page to document the link feature? I would call it "Link to a profile", and place it right under "View someone's profile" in the left sidebar. You can follow the patterns from similar pages for how to do the instructions, and I'll be happy to do an editing pass.

[Pratik2026]

Sure, I am on it!

[Pratik2026]

@alya , I've added a help center page as suggested and also made updates to the icons within the help center pages.

[Pratik2026]

Thank you for the feedback, @alya. I've updated the help center page as suggested.

[Pratik2026]

@alya , Just wanted to know if there is any additional feedback?

[alya]

Sorry I lost track of this PR! @sahil839 could you please do a review pass?

[Pratik2026]

@sahil839, This PR is ready for another round of review! Please let me know if further changes are required.

[alya]

@sahil839 just making sure this is still on your list to review.

[sahil839]

Posted one comment. Looks good otherwise. Would be good if @karlstolley can also have a look on CSS changes.

[sahil839]

One improvement can be if the refactor commit can be the first commit, that would remove the unnecessary changes in the commit which changes the icons. You can do this change if that's easy to do, otherwise it is fine.

[Pratik2026]

I've removed the formatting changes. Also, Now the refactor commit is the first commit as suggested.

[sahil839]

Uhh, sorry, but I still meant to keep the changes for CSS refactroing and updating the icons in separate commits, with only order being changed, which would make it easy to review.

[Pratik2026]

My bad, I've now kept the CSS refactoring and updating the icons in separate commits with proper ordering as suggested.

[sahil839]

Looks good. @karlstolley pinging you in case you have feedback regarding CSS changes.

[karlstolley]

Overall this LGTM. It would be nice to clean up the underscore-style classes and replace them with hyphenated versions as a prep commit.

[Pratik2026]

As suggested, I've added a prep commit that replaces the underscore-style classes of the user profile modal with the hyphenated one. @karlstolley, please let me know if further adjustments are required.

[karlstolley]

Those hyphenation prep changes look good, but the commit message should probably be prefixed with "profile_modal" or something more specific than "css," as the message as written doesn't make it clear enough what specifically is being changed.

[Pratik2026]

The commit message has been updated.

[karlstolley]

Commit message looks good, but as a prep commit, that should be your first commit, so that the substantive changes here already have the hyphenated class. git rebase -i is your friend here, and you might have some merge conflicts with yourself that you'll have to fix as you go.

[Pratik2026]

I've reordered the commits as suggested.

[alya]

@timabbott looks like everyone's feedback has been addressed. @timabbott let me know if you need me to re-test.

[timabbott]

I reworked this to address that last batch of feedback and marked this to merge once CI passes, thanks @Pratik2026 and @karlstolley!

[alya]

And @sahil839 . :)
