Answer 2

It's not clear what you want. If you want to make the word "technique" on the same gray background as iphone .. then for the "link" with the .technicsbtn class, change the background color and text color. And for the .technics-content2 class, you can not use the background at all in this version.
If at all the "technique" should be on white, then we remove the background altogether.
If ... in general, the options are dark. What exactly is not working for you?
