Hi,

Please try use this code:

\
.post-entry a{ font-weight: bold; }

Also, I think you should check Envato Support Policy for all items on Envato  here

The Item customization doesn't include in support requirements - while you've requirements us too much questions for item customization - like on this ticket. We will can't provide support for item customization for you anymore in the future. We can't do that for each customer because we have near 16k customers use this theme.

Hope you can understand it.

Best Regards,

PenciDesign
