If you are building your website in Divi and come to the stage of testing, what you have created on multiple screens and devices, a common problem of words breaking or splitting across the screen, can come up. If you are using Divi theme, which is what I use, then the solution is simple.
All you need is a line of code in your CSS:
h1, h2, h3, h4, h5, h6 {overflow-wrap: normal;}
