Further customisation

Hey guys!!

You were all really helpful before so I wanted to ask for some more help ??

My blog is https://www.ohkay-dohkay.com and I use the adelle feel, I really like it but I am new to this.

I am looking to add a second sidebar on the left of the blog and to ensure the emu runs over it the same as it does on the right. Kinda like beckybedbug.com and dorkface.com.

I am a novice so am using css.

Thank you
