can u help me write the code? i want bold black color, and where should i put it in the top or bottom? thank u

Go to Customize Theme>Collection Page>Product Grid Section

Then in the Custom CSS settings try adding this:

.text-theme-light {
  color: red;
}

If that does not work try this:

.text-sm {
  font-size: .88em;
  color: red;
}

This should be the result:

I hope that helps!

Hey @Yasmeen12

You can not make changes onto Shopify but if your vendor is appearing somewhere else on the website except product page then let me know.
