unfortunetly it’s not that easy. i’ve done similar adjustments with other themes but my css is limited. you can find the CSS file here:
https://www.lightword-theme.com/wp-content/themes/lightword/style.css
there are several #content-body and .content-sidebar lines. you can adjust the witdh of the sidebar with this line i guess:
.content-sidebar{width:191px;display:inline-block;overflow:hidden;vertical-align:top;}
but how do i adjust the outer section of the sidebar? it always gets drawn below the content when i expand it to 300px.
@esmi i didn’t set the blog up yet. still experimenting offline with xampp.
