FontAwesome not warned PageSpeed ​​Insights

By Mạnh Cường Nguyễn Updated: 04 Jan, 2019
Insert the font-awesome.min.css in the usual way that is still used by most web pages, as it does not affect the page load time. However, when you use the PageSpeed ​​Insights page, your site will be warned with an error. And to remove the error, it is best to replace the font-awesome.min.css link by inserting the direct css of the font.
FontAwesome


Directly insert FontAwesome in Blog


Method 1: Insert the tag    <b:skin></b:skin>


Copy
<b:skin ><![CDATA[

/* FontAwesome */

]]></b:skin>

With this insertion, you also do the same with the Material Icon, for example:

Copy
<b:skin ><![CDATA[

/* Material Icon */
@font-face {
  font-family: 'Material Icons';
  font-style: normal;
  font-weight: 400;
  src: local('Material Icons'), local('MaterialIcons-Regular'), url(//fonts.gstatic.com/s/materialicons/v12/2fcrYFNaTjcS6g4U3t-Y5ewrjPiaoEww8AihgqWRJAo.woff) format('woff'), url(//fonts.gstatic.com/s/materialicons/v12/2fcrYFNaTjcS6g4U3t-Y5ZjZjT5FdEJ140U2DJYC3mY.woff2) format('woff2'), url(//fonts.gstatic.com/s/materialicons/v12/2fcrYFNaTjcS6g4U3t-Y5bbKic1PW3nceB3q24YFOMg.ttf) format('truetype');
}
.material-icons {font-family: 'Material Icons';font-weight:normal;font-style:normal;font-size:inherit;display:inline-block;line-height:1;text-transform:none;letter-spacing:normal;word-wrap:normal;white-space:nowrap;direction:ltr;vertical-align:middle;
