Question

css

There is one site at the end of which there are a couple of blocks with icons, font-awesome is connected, but 2 icons are not displayed.

If at the very beginning, in the CSS file, reconnect the library by writing this, then everything works.

@import url ("https://netdna.bootstrapcdn.com/fonz-awesome/4.6.3/css/font-awesome.min.css")

However, copying styles from this file does not solve the problem.
Everything would be fine, but you need to make sure that the css files are located on the internal server, without links to external sources...

Answer 1

you have font-awesome connected as many as 3 times - 2 times in head ´
and once by importing, which is what you indicated -
one of the ones connected in head, 4.4.0, the other two show 4.6.3, of which what connects with bootstrapcdn apparently just includes those icons that are not in others.
Remove this leapfrog, connect the desired version only once, no matter where, and everything will be fine

Answer 2

Use the icomoon.io service with it you will not have any problems)

Answer 3

However, copying styles from this file does not solve the problem.

No mysticism, there are no styles in local css: .fa-envira and .fa-sign-language
