How can I remove text highlight from main titles?

[IanDang]

The text is highlighted for some reason. It has it for all the main titles. Can someone help me delete it?

@IanDang
you mean it’s boldness.

You fixed the main page but all the other pages have the pink highlight at the bottom

[Zworthkey]

.page-title, .shopify-policy__title h1, .shopify-policy__title .h1{
background:none !important;
}

@IanDang
Add this code in the bottom of the theme.scss
