R Shiny: downloadButton styling and icon -


is there way change icon or @ least control padding of downloadbutton in shiny?

i've tried setting class:

downloadbutton("html_link", label = null, class = "download_this")

then in css:

.download_this{     height:40px;     width:57px;     color:blue;     padding-top: 3 !important; }

this changes size , color, reason padding doesn't work on icon , appears high on button.

it seems error in .css , css padding generates space around content, 3 means nothing css, try:

padding-top: 3px
