In this video I am showing you how to customize the fonts in wordpress. Its very easy and free. You can set it globally or for a small piece of content.
The "Easy Google Fonts" plugin is awesome if you want to set it globally or you want to customize the size, color, margin, padding and things like that.
The "Use Any Font" plugin is great if you want to use custom font or different font somewhere in your posts.
Tell me which one you like more? Also feel free to request a video :)
