Drupal 8.x

I made a module with a form called SimpleForm which consisted of 2 textfields and a submit button. However, I cannot open the form using the path, it always throw HTTP error 500. I also couldn't show the form on my twig file. Can someone please have a look at my code and give me a proper explanation? Thank you beforehand.

Hello, 

Structure > blocks > custom  blocks > block type > add a type. 

Added a block type there. 

Manage display of the block type > added 5 fields. How can I create a block layout similar to display suite module?

Header

left and right region

Footer

So I can place fields in the regions. Above is an example of layout. 

Please advise!
