[lunny]

Thanks! But on my local, I used chrome on Mac. collaboration still has a slight problem and could you also fixes branches UI?

[Morlinest]

@lunny I've already send PR to fix branches UI, check #1435 pls

[lunny]

@Morlinest great for that. and the collaboration issue?

[Morlinest]

@lunny Can not reproduce. Tested on Chrome, Firefox, IE 11 and Edge on Windows. I do not have Mac. Everywhere it looks good (as on my screenshot).

[sapk]

I will test it in few hours. Look good at first glance. Since you remove the .item:not(:first-child) for top border. have you check templates/user/settings/account_link.tmpl , templates/user/settings/applications.tmpl, templates/user/settings/email.tmpl , templates/user/settings/openid.tmpl ? They should simply need .divide maybe.

Maybe https://github.com/Morlinest/gitea/blob/66a9b96824cf1912fc75632c1c7b3dbc37f7c7a1/public/less/_repository.less#L1386 could also be remove ?

[lunny]

Since #1456 is merged, should we close this one? @Morlinest @sapk

[Morlinest]
