Front End Bootcamp

Synopsis

This course will teach you everything (and quite a bit more!) to become a Jr. Front-end Developer at a company of your choice. It begins with a firm grounding in the basic language of the web, or as I call it the "structure of the web", HTML.

If HTML is the "structure" then surely CSS is the "look and feel". Without it, your HTML will not look good, and the display of your HTML will be at the whims of the browser (Chrome, IE) that you render it in. CSS tames the structure of HTML into a beautiful, visually appealing "web page"

I then move you onto Javascript, which is certainly where you start your first 'real programming'. I describe Javascript as the "usability" of a "web page" because too much and your page is not usable, not enough, and it could be more usable. With Javascript, you can make pages more 'interactive' and reduce 'page loads'.
