We have used ET-Line icons in our bobby template, we have loaded all the icons which come with the ET line icon library, unfortunately the icon provided not providing the Instagram icon. but don't worry about it we have an alternative. we have also included Fontawesome icons in our bobby theme.so you can use font awesome icons for this. I have added the Instagram font in your footer. kindly check this out. also, all fonts are displayed now.
Please do take some time to read through some of these links:
