Hi Leona,
I installed your theme on my server to take a look.
First I have found that the text of ‘Featured Area 1 to 3’ is a picture.
So to replace it, it take to create your own pictures. You can use online tool Canva for that.
1. create pictures size of 282px x 66px
2. Run them throuth tinyPNg site to make size Mb/Kb the best.
3. Upload them to the site over Dashboard/Media
4. Go to your Dashboard/Appearance/Customize
New Menu Opens
5. Go to Theme Options/Homepage (Featured)
6. Upload new pictures for Content Area 1, Content Area 2, Content Area 3
7. Save all changes !!!!!
8. Enjoy your life
I hope Im helpful
Cheers
