I am a recent college graduate, I am looking for a web design job, but how can I get a job and get professional experience if I don’t have any in the first place?

one thing you can do is creating an online portfolio to kindof showcase your work.

getting the job portion might be a bit harder, you may have to start out as a intern first, or even at a different position.

Besides that, you can do stuff such as volunteering and helping them with their IT needs i.e. there webpage.
