Adjust the width of 2 column section (text and image) into small and big columns (Be Yours Theme)

[CJames]

Hi Coders, 

I'm trying to adjust the width of a 'text and image' section that is currently 2 equal columns, into columns of varying sizes. for example, the first column should be smaller (about 1/3 of the page width on desktop) and the second column larger (about 2/3)  

I believe you can use 'calc' - for instance I see that grid item width for each column currently uses -- calc(50% - var(--grid-horizontal-spacing) / 2)... etc But, I'm not sure how to write what I want in CSS.

Hi @CJames ,

We checked the site but could not find the section you mention above. Can you give us more info on the location of the section on the page?

The info can be page name, section name, etc.

Thank you!
