I have some experience in cad/cam software but little else. It was recommended to me to look into a career as a web developer. I was told it should be something I could do well at and that it shouldn't take too long to get a good grasp on the essentials that could get me in the door somewhere. How long should I expect it to take me to get to that point? Also, what online resources are available to help me learn the basics of web development? I have almost zero knowledge of HTML, CSS, PHP or Java script. I only know that these are key elements of web development.
