I want to use a parent theme to create my own child theme and basically create a completely new look so that the old theme is barely recognizable ( I don't have the knowledge to start a theme from scratch ). I am fairly new to all this and don't know much PHP and CSS and I wondered how much I will need to know to completely re-design the parent theme?
So For example I would use twenty eleven theme as that seems to be suggested by most places to easily customise, and then I want to re-design my own website using this theme as a base and then install plugins for sliders, footers, headers, menus etc. is this possible? Also will people be able to tell I have used a parent theme?
