Jeshua 3 is the third WordPress theme I’ve made for my personal site. You’re looking at it right now.
This theme was developed using the latest front end principles and technologies. The theme is mobile first, displaying well on mobiles, tablets and larger desktop displays; at the desktop/tablet break point a CSS3 transition eases the user into the new style, while the navigation displays differently to best suit tablets and mobiles. Hell it even looks great when you disable JavaScript. To create this theme I employed SMACSS, a version of object oriented CSS. The CSS is processed by SASS using Gulp to run these tasks automatically. There is minimal javascript, but DOM manipulation is achieved with jQuery.
The code for this theme is available on GitHub
