Reconversion web design

Hello there!

I'm 39 years old and looking for a professional conversion.

I have a graphic designer background as I've worked for 7 years in the print and signage industry. I know Illustrator pretty well, and all the Photoshop basics + some wordpress notions.

I'm currently looking into q myriad of online course to become webdesigner and I'm a bit lost of course.
I would like to read from someone who followed a similar path and learned webdesign online. What is your experience with online courses and what would be your advice for a start ?

Do you even recommend to become website designer knowing how fast the tech is growing ? Is there any room left for a beginner to become freelance ?

Thank's for help :)
