Nah you can wing it easy man. Just pretend to know a little about CSS and HTML and you are ready to be freelancer. All you need to do is cut and paste some code from other people and pass it off as your own. Nobody will ever sue you or something. I mean that only happens in hollywood films. You will soon be wealthy and can drive around in Ferraris. Piece of cake really. Oh ehm just in case. A freelancer like myself in general prides themselves in knowing vastly more than employees. And being able to deliver quality code and solutions in situations where an entire team is stuck in internal struggle blocked by structure or other factors. We tend to produce a lot of unique code and guard that with NDAs and ownership clauses. And I have not met a single freelancer who struggled to know the finer details of data elements has trouble making a JSON island does not know what AJAX is or has no clue on CSS selectors. I recently made my own SVG library. I might be the first to ever create barcode 128 directly from SQL server. Look I am not saying this is not your profession it could be but I suggest you quickly drop the attitude that freelancing is something simple. It is hard work in addition to maintaining client relationships cold canvassing taking care of your bank and a fair bit of meetings. Oh and driving around in a Nissan 37Z
