API shortening - CSS animations and transistions

Some details in the readme but, I would very much welcome advice on the following issues:

• I have failed get the final of the three svg icons working properly. I spent a long time on this and still failed. I need to have an approach to standardize icons of different sizes. Any suggestions on how to do this are most welcome.

• have struggled to off-set the introduction section banner image. I tried translate and positioning, but it always resulted in horizontal scrolling. I have not got an approach to deal with this kind of issue that I can fall back to. Any suggestions would be very much appreciated.

• When I add a single result the JS renders the entire containing element meaning that all the li elements animate in again rather than only the one just added. I have had this issue a couple of times now and would appreciate any advice on how to make a change that affects just the item added.

Thanks!
