Thanks for the reply. I have tried the copy and pasting route previously but the code somehow seemed incompatible with sublime text and notepad+. I remember it not displaying properly anyhow. That said, I am a total novice and probably did something wrong.
The CMS on which my site currently runs is probably one of the biggest issues. I do have a login but adding content is the most frustrating task at the moment. Everything is laid out in tables and there are very limited options for me to change. If I want anything major done I have to email the company and request it, then they code it in.
They have also quoted me for converting the site to responsive but it seemed a little expensive based my on limited knowledge of how "easy" it was to convert a site.
