I'm looking at this site: http://www.calgaryclimbing.com/rates/ . On their footer they have very clean looking icons that link to their social media pages. I want to do the same using the same icons they are using. But when I inspect the elements It shows that they use an i tag and that the class links to some css code that uses the content property. I want to use the image icon so my questions are how can I get the image? And why was it programmed this way? Why not just use an image that you could click on?
I didn't check the link you provided but it's most likely a custom font just like Font-Awesome which you can use to put many kind of icons in your Web Site/App.
Font-Awesome use the
<i> tag as well just like you explained.
Why using Font-Awesome? As they say:
Font Awesome gives you scalable vector icons that can instantly be customized — size, color, drop shadow, and anything that can be done with the power of CSS
