Help With A Little Css Please

I would like to close this corner:

This is my website: [url=“In WhatsApp teilen”][/url]

Some suggestion? thanks! 8)

It seems the problem is solved when the border width is 1px.

Try {
border-bottom: 0px !important;

Thanks for your suggestions @cscartrocks and @eComLabs

the problem with this:

[size=3][color=#696969] {[/color]

[color=#696969]border-bottom: 0 !important;[/color]

[color=#696969]} [/color][/size]

Is that produce a kind of “jump” in the elements: [url=“”][/url]

annoying. if there are some tip to fix the jump this issue will be resolved.

I really appreciate your help.

Thank you guys!
