So here are my questions plz number answers to correspond and thank you for any help!!!
1.. What is child theme i really don't understand it.
2. Do you know anything about responsive theme with child theme saves all your work.
3. Are there any other layouts for responsive because in about a month i am doing a different website but love responsive.
4. can child theme be added to my website now or did it have to happen from the beginning.
5. is there a big learning curve with adding child theme whereever it is found (if you know plz tell me), because I am very new.
6. this is a BIGGIE that i think i just figured out but not sure....if you have a theme, and you want to change it can you keep the theme loaded deactivate it, and then download another theme and activate it, will it switch over, and then if you don't like it reverse process to go back to original, and will work be lost?
thanks!!!! i really appologize for so many questions but i work full time and when i am doing this this all comes up at once and then it's the next day with answers sometimes so thanks everyone. cj
