How to change border-bottom of page headers

Hi there Aigars and Co!

Just wondering how to change the border-bottom of page headers - i.e. About, Contact -(excluding main/front page and posts). I used the following to change pages to no avail (every page header was changed - main page, other pages and posts):

.page-header {
border-bottom: 1px solid #dd0000;

Any assistance is greatly appreciated!

Hi @4alex,

I hope you are well today and thank you for your question.

You can try using the following CSS code to achieve it. .page-header {
border-bottom: 1px solid #dd0000;

Best Regards,
