What skin are you using?
Is this the front page?
Please provide URL.

yes this front page
skin type :normal
version :6.8.2

Not sure there is a normal and please provide URL so the problem can be seen live.

this issue am facing in local development instance,URL may not work for you

@kalavathi OK no url

Is the skin the bootstrap forum, please be exact so I can check the files and maybe install it to see if I can how your problem appears, if it does, on a clear skin install etc.

Looks like an ipad or other device too. Correct? Makes a difference as it is different css than a desktop.

While in your forums, click skin in the evo bar menu at the very top of the page. The next screen will tell you what skin the forum is using.

I found it. I don't see the lines even when I use firefox mobile view. Maybe you got it taken care of. Looks like bootstrap but modified/restyled from the original. So wally world is using b2evo?

Hi, I'm not post #6(but I play one one TV) but in my second screenshot in #8, you can see "development_forums_skin", which is a custom skin most likely developed by whoever developed or is developing the site or the forum part of it at least.

My first screenshot shows a representation of an ipad as seen in firefox's mobile view mock up, which is not 100% accurate.

That is why I asked what device you were using for your screenshot.

Between a custom skin and lack of knowing the device, it's difficult to diagnose and impossible to reproduce the problem.

"Device" may be a tablet and the browser you're using would be good to know as well.

skin : devportal_forums_skin
browser : chrome, firefox
device :desktop

Can't find that specific skin, so can not look at it live. Have you tried a different skin like [bootstrap_forums_skin]

It's a custom site that has b2evo integrated with bower package manager.

skin : devportal_forums_skin
browser : chrome, firefox
device :desktop

I have firefox and chrome and I don't get those lines even with the browser window resized.

Half or more of the css styles seen in ff inspector are coming from a 'bundle.css' which is bower I believe.

<link type="text/css" rel="stylesheet" href="style.css?v=devportal_forums_skin+6.8.2+6.8.2-stable-2016-11-17">
https://developer.walmart.com//build/bundle.css

Either they made a copy of bootstrap and modified it and/or they're using stylesheet from bower.

There are misspellings as well so that could be a problem. (one instance of containerr - and one of container) I also saw (footer - footerr)
