Can a yellow period be added on the home page?

Is it possible to add a yellow period after a word on the homepage?

I’m trying to create an effect that has 3 periods total, one after each word.

Hello there,

I hope you are doing well today.

The period should appear automatically simply go to Appearance > Customize > Jumbotron Section and add a word to the First, Second and Third word from title.

Best Regards,

Home page: I have the yellow periods after the 1st 2 words, but would like it after the 3rd as well. Can you help

On all pages, would like to add a yellow period after each page header text. Can you help with this as well? (for example after About Us in the header)
