Cant add border to just one section instead of all

I am trying to add a border to this section of my website:

But when i do this using the thickness slider it also affects the rest of the section in my website:

is there any way i can make it so only the section that i want to have the border has it.

@julianojg - can you please share this pagelink?

@julianojg - will need to make something like this

I would like this while not affecting any other section on the page:

@julianojg - it will l not affect any other section, if you want like my screenshot above then add this css to the very end of your base.css file and check

#shopify-section-template--20272456925482__14ed8410-be5e-4bb0-81fd-a7b75b33bb58 .page-width{border: 1px solid #fff;}

@media screen and (min-width: 750px){
#shopify-section-template--20272456925482__14ed8410-be5e-4bb0-81fd-a7b75b33bb58 .page-width{margin: 0 5rem;}
}

@media screen and (max-width: 749px){
#shopify-section-template--20272456925482__14ed8410-be5e-4bb0-81fd-a7b75b33bb58 .page-width{margin: 0 1rem;}
}

in my case the code needed was

.image-with-text__content{
    border:none;
}

this was added to the bottom of base.css

@julianojg - great that you solved your issue
