COLUMN ADAPTIVE

I need help. I would like the column where is the text under the image (see image) is fixed at the top and the base image without the amount of text to influence the height of the column. This is possible by custom css?
/
Notice in the image attached.

How do I always keep this column always leaning on the top and bottom of the image regardless of the amount of text?

To realize this use the mouse wheel to scroll down and the page.
