TinyHouseopia is based on a single content column. The single column makes it much easier for headline and text purposes and accommodates cellphone viewers quite well. Immediately after the page is uploaded, I go check out how the site looks on my Smartphone and then go make necessary changes.
SBI/SiteSell has options on their text blocks, headlines, anything really, that needs to be viewed only on a PC/Desktop, or only on a Smartphone. That's why responsive websites are so popular today. Actually, that feature is a necessity now in my humble opinion.
I hope you enjoy seeing my designs and I look forward to working with you on your SBI website — as I absolutely live, eat, sleep, and breathe this stuff :-)
