I am trying to make 2 columns with 100% height and 50% width using Bootstrap. The screen should be divided in 2 sides, left and right. I tried other solutions here and nothing seems to work. More than sure it is because I miss something.
In the left side I want to have an image centered vertically and horizontally
In the right side I want to have only some text.
Thank you very much for helping me!

Here is my code

The problem is that the container does not even get to 100% width.
On mobile I want everything resized to 1 column and 2 rows.
