Helping a client who built his own site convert it to mobile-ready. The new version is in a sub-directory of his public server. Today I realized he thinks I can automatically migrate HTML changes he makes in public dir into the version in the sub-dir. I told him my software (NPP and Sublime) can't automatically do that, but I'm wondering if there something out there that does? FYI he writes a lot of inline CSS that I have to push into an external sheet.
It depends on your requirements, which type of web page you want to create. The knowledge of HTML, CSS and other tools to be good, because customer expectation should be fulfilled in your design.
