Mobile Share Button Appearance

Hi AddtoAny Support,
Thank you for the wonderful plugin. I have a quick request that I think other AddtoAny users will find helpful if there’s a solution for it. May be a great addition to the AddtoAny customization page.

We’d like to modify the appearance of the floating share buttons for mobile where the hortizontal buttons cover the entire bottom of the screen in either portrait or landscape orientation. We know that the exact width of the buttons can be specified using custom CSS although we’re hoping there’s a “100%” width option using CSS so that they’re flush to the sides of the screen with no spacing in between. Here’s a visual example of what we’d like to do:

– Portrait: https://www.dropbox.com/s/x4gejr5v9yn8wzl/IMG_6519.PNG?dl=0
– Landscape: https://www.dropbox.com/s/i0yh6g0nolrapqx/IMG_6520.PNG?dl=0

Note how the buttons expand or shrink according to the orientation fitting perfectly regardless of screen size. Thank you in advance for any help you can provide. Cheers!
