Moving sidebar to the left side?

here is my style.css for the theme: https://pastebin.com/i3mKCeF9

Almost impossible to help without looking at the site itself…just CSS isn’t really adequate info.

Can you provide HTML of the page?

You can achieve this

By adding

• float: right; to <div id="content">
• margin-right: 30px; to<div id="content">
• float: left; to <div id="sidebar">
• margin-left: 30px; to <div id="sidebar">

Where would I add that code?

Are you using a custom-built theme?

I think. I added it through wordpress theme search.

If it’s not custom, you should be using either a Child Theme or Custom CSS plugin to implement modifications.

How can I tell if its custom or not? The style.css does say it was based on another theme.

Did you download the theme or did you create it from scratch?

I downloaded. So I should either make a child theme or use the plugin?

Up to you.

I still do not know where to add the code? Do I add it to the style.css file or another php file?

Which have you chosen, a Child Theme or plugin?
