Remove heading/text underlining

I am trying to remove the underlining that appears on headings.

The reason for this people keep telling me the words are spelt correctly, so why is the spell check showing it as incorrect.

Any help will be appreciated.

Hello there,

To remove the widget title underline, could you please try to add the following CSS code through the Simple Custom CSS plugin or child theme’s style.css?

.panel-grid-cell .widget-title:after{
  display: none; 
}

Let me know how it goes.

Regards,
Kharis

Thank you Kharis Sulistiyono. That worked 100%.
I was trying to apply an underline rule to the page, but I now see it’s the widget that needed the rule.

Thank you.
