On Monday, the startup will launch tutorials for HTML and CSS, its first non-JavaScript courses to date.
While JavaScript is used to build applications, HTML and CSS are the basic building blocks of webpages. New programmers typically learn how to use them before any other programming languages, and by including them on its site, Codecademy will become a more viable option for true beginners.
"[They can be used to accomplish] the fundamental things you want to do when you’re building a website," Codecademy co-founder Zach Sims tells Mashable.
The site hasn't exactly had trouble attracting new users to its game-like lessons. More than 400,000 people, for instance, have signed up for its New Year's Resolution course alone. A bigger hurdle for the startup has been growing its content in pace with its user base.
In January, the company announced a solution for this problem. A new teacher tool gives anybody the option to submit a lesson for the curriculum, thereby making Codecademy content curators rather than creators. Sims tells Mashable more than 2,000 lessons have been submitted, including those that compose new CSS and HTML curricula. User submissions will likely contribute to courses in other languages soon.
"[CSS and HTML] are the first of many languages to roll out in the near future," Sims says.
Codecademy's new HTML lessons show users how their code looks on a webpage without leaving the lesson page.
