How to remove side strips from HTML buttons on smartphones?

Hello.

I wanted to add two buttons with links in html. All works good but on smartphones, some weird strips pop up on the sides. See pic below. How can I remove them? Thanks in advance.

  1. In your Shopify Admin go to: online store > themes > actions > edit code

  2. Find Asset > theme.scss.liquid and paste this at the bottom of the file.

.stripe{
display:none!important;
}

Thanks!
