Have you heard about books? I know knowledge in a book is mostly not free because of lecturing and packaging but books are a really good starting point. Especially the bold ones!

To be honest.

Online courses are great sources for beginners but if you wan't to go to advanced things you have to pay their pricing plans. I have a good html 5 Book here at my book shelve and paid about 50 € for it.

If books are not the way you like to learn than you can take a look at Video2brain and pick a course about html 5 programming or pay theyr pricing plans. Thay are owne by https://bbs.deepin.org/module now but linda.com was an is a good place to learn things as before they bought them to expire their marketing power to germany. But their videos are also not free of charge and , again,a pricing plan may be a cheap solution but a good book is the cheapest one.  

If you looking for an other online vendor for good courses take a look at

Tahn there is Treehouse

A third way may be the good old youtube. If you are lucky You'll find a funny teacher.

And the last way I like to mention is a real course driven by a software developer agency. These courses are really expensive but also really really valuable. You sould take a look at google if you like to go as far as possible from your hometown to get knowedge in a good course fro programmers somewhere nearby.

books can be good but they can also be a huge waste of money because you don't have much to go on about how good they are besides someones review and free chapters or something.  if you do plan to buy them though maybe buy books on sales like 'day against drm' for ebooks on oreilly books site or other book sites that offer big sales, that's the only sale day i know about.
but there are free things on the internet to use but it all depends on what kind of specific programming thing you want to look into so you know what to search for
like this https://handmadehero.org/ is a good place to learn to code but it's focused on making a game so if you don't really care about making a game, you can still learn a lot about programming that can be applied in other ways but it may not be exactly what you are looking for
or this http://www.jongware.com/aow/aow1.html  isn't a programming tutorial at all, it's a guide to a file format used for a game to store image data, but by reading it really helped me understand how programs store data in files and use them after
another ex http://aluigi.altervista.org/ has a lot of nice information because it has a tools with source code that one can learn a lot from if they want

i guess my point is that there is a lot of information to find you just need an interest and idea of what you want to find.  just dont be too quick to spend money always look for the cheaper route first

I was hoping for good free or low-costs options.  I use YouTube and Lynda also.  I don't care for books because it's not interactive.  I've found more since posting this:

Codecademy
CodeHS
