HTML and CSS Reference
Once style.css is saved, the index.html file will show the
icons stacked one after another because there is no
float property added.
This happens because each “ ico ” class is going to be
rendered as a block element since that class comes
with a display:block; property included.
So the next step is to add the float property for the
Facebook icon only and the space between icons.
What other options can you have here? Maybe the
“ display:inline-block; ” property?
