Oh - in preparation, spend some time on either of these sites (if you haven't already). Both provide free resources for HTML, CSS and JavaScript and much more:

https://www.w3schools.com/
https://developer.mozilla.org/en-US/

The mozilla site is more accurate while w3schools is more user friendly and easier to navigate. I personally haven't found any errors on w3schools, so I think they have cleaned it up.

Some areas to make sure to cover independently if they don't cover in your coursework:

• Mobile first design
• Responsive Design
• Bootstrap and/or flexbox
• JQuery
• Make sure you learn to hand code, don't count on a WYSIWYG editor to do it for you. I have never been able to afford Dreamweaver so I have always used html editors and taught myself hand coding.
• There are others too.

Let me know if you have any questions.
