disable forward,backward button in browser

I want to make a blog/article website with one or two products available to buy online in time. I'm finding wordpress loads times very slow so was considering doing away with it and making a custom site. I haven't got loads of css/html/php experience but am happy to learn. Am I best off sticking to a cms system like WordPress or Drupal or learning some more coding and using Ci?

Thanks.

Even I think you can not do that although, You can try this https://www.irt.org/script/311.htm this might be helpful in your case.
