Alignment of text with background colour beside image

Hi there

I have a block of text with background colour behind it by using:

/* otbs green backgound to text*/
#block-yui_3_17_2_1_1568246902220_52426
{background: rgb(40,171,74); padding-left: 30px; padding-right: 30px;}

There is a graphic image beside the text. I would like the depth of the green block of text to match the depth of the image as screen sizes / formats vary. At the moment, as the screens reduce the images shrinks compared to the green text box.

The problem occurs at the bottom of the first project.

Any suggestions?
