Mobile Site Solutions?

Hello All,

I launched my company website (desktop version):

https://www.gtlightingandelectrical.com

However, when I view one of my pages, (https://gtlightingandelectrical.com/wordpress/products/lighting-fixtures/) on my smartphone, the images are stacked on one another instead of side-by-side, and the text is mis-aligned.

Question: If I utilize a mobile site plug-in, will this issue be remedied when viewing my site from a smartphone? If so, any recommendations on a plug-in?

Thanks in advance.
