Elements float

Hello,
I’m looking for solutions about a tiny problem.
I need to pub an image on the left with a text on the right, and those elements are already in a column (so I can’t fix the problem by putting two columns in one bigger column). I tried by creating custom css (see below) and applying a float left on the image and float right on the text, but it still doesn’t work.
One solution could be “code block” but I rather use image/text elements.
See the link of my website below. Thanks for helping.

.floatleft {
display: inline-block!important;
float: left;
width: 29%;}

.floatright {
display: inline-block!important;
float: right;
width: 70%;}
