Evanto tuts+ offers both video and written tutorials and courses on many subjects related to programming for the web, design and photography.
The full video courses are for subscribes only (a monthly fee for all the courses) but the how-to videos and tutorials are free and are very detailed and well done.
The also have a youtube channel which is updated often and contains mostly short tips and tutorials but also occasional longer courses.
The website is easy to navigate either by searching or browsing by category.
I would recommend checking the how-to tutorials which they post often (free) and you can also subscribe to them by category. Review collected by and hosted on G2.com.
