Fontawesome in nav and social icons not showing up for everyone or on mobile

I am seeking help as i have been at it for hours

I have been trying to add a search icon to the header of my site using font awesome (open to other solutions if recommended) . 

I have tried 2 methods - adding it to the navigation with a :before pseudo however i had to have an actual navigation title so i just used a period so i didnt have to have the word search and just use the icon - not ideal). 

I used this code in the code injection header

This CSS in trhe Custom CSS

// ** Search icon in header. ** //

.header-nav-item:nth-child(9) a::before { 
content: '\f002'!important; 
font-family: FontAwesome !important;
display: inline-block;
padding-right: 0px; }

I thought htis worked until I checked it on mobile and shared it with a few colleagues to review,  As seen in the screen capture i see it fine on desktop Chrome but it renders as a sqaufre on mobile and for other uses.

I then found this solution in the forum for adding font awesome to the social icons in header. Same results - redners fine on my desktop but not on mobile or for other users.

using the enclosed CSS

// ** Search icon in header. ** //

.header-nav-item:nth-child(9) a::before { 
content: '\f002'!important; 
font-family: FontAwesome !important;
display: inline-block;
padding-right: 0px; }

thanks for any help you can provide.

It looks like you need to link the fontawesome stylesheet to your header code injection. 

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

Thanks I really appreciate you responding- unfortunately it is still not showing up on mobile in either location (social links or nav)

If FA 4.7 doesn't work, try FA5.

Or you can use CSS to insert search image, instead of FA icons

Or use jQuery to add search image on header (i did this for a site last week)
