remove borders in parament theme

In your css file you need to comment out one of the styles so that it looks like this:

/* #branding.has-image, */
#menu,
#introduction,
#respond,
.bypostauthor .comment-meta img,
.commentlist article,
.commentlist .pingback,
.entry-byline,
.hentry,
.widget {
	-webkit-box-shadow: .2em .2em .3em rgba( 0, 0, 0, 0.45 );
	-moz-box-shadow: .2em .2em .3em rgba( 0, 0, 0, 0.45 );
	box-shadow: .2em .2em .3em rgba( 0, 0, 0, 0.45 );
}

the idea is to keep all other styles as they are but to remove the branding from that group. This is under a section called shadows.

Hope this helps.

thanks for your response but that sadly didn’t help :/

@mytaxsite.co.uk answer is correct, just be sure you removed it from line 111 in rtl.css and not style.css as your site is in Arabic which is a right-to-left language that css is automatically included by WordPress.

If you use the browser’s inspector you can quickly find css you need to tinker with.
