prioritize visible content problem in mobile version

Could you provide me with a link so that I can check what may cause your issue?

Hi,

Below my website sort link

https://bit.ly/1OZUpQp

It seems like either the post title or post thumbnail is sitting too close to the post category link.

Try this to see if this solves the problem. Also clear cache afterwards.

.post-title {
    margin-bottom: 5px !important;
    padding-top: 5px !important;
}

In which file can i try this code ?

You need to paste the snippet somewhere in your CSS stylesheet (style.css).
Please use a child theme or changes may get lost in a future update.

This is not solve my problem.
any other way ?
