After customising quite a few surveys in Qualtrics, there are some elements that I've repeatedly struggled to adjust to my full satisfaction. Does anyone know of a canonical reference document that shows the CSS relating to Next and Back buttons (especially their position - I can only ever get them to show in the bottom-right of each page, next to one another)? I'm also having difficulty with matrix questions - I can't figure out the CSS that controls the 'fade on hover' behaviour for alternate lines. I have a darker shade behind every other statement / ranking line, which currently fades to white on mouse-over and I'd like to disable this behaviour. Any help appreciated!

In general this will all be theme dependant. You can use your inspector to find out more about the document structure and element ids / classes.
