Hi Techlyser_web. I’m so glad that you gave me a valid solution.
But after changing my code, I found out that some parts of the overline text were changed as I wanted, but some didn’t.
If you scroll down to our homepage, you’ll find some unapplied overline texts. Can you find out why?

Also, please give me a link to give you a cup of coffee 
Thanks!
