I have been working as a freelance web designer now for over 2 years, building websites using plain html, css and jquery.
Most of my clients require simple showcase websites that look well, load fast, well optimised for Google, are easily navigated and show a portfolio of projects. Most also require a blog.
My question is, what is the level of knowledge required in order to take a static html, css website and add Craft CMS to it. The only areas of the website that I would want my clients to have access to would be for them to complete simple tasks such as adding on another project page with an image slider and project details or to add a blog post with a few pictures.
I have little to no knowledge of PHP and don't have the time to learn anything too advanced.
All replies would be very much appreciated. Thanks.
