Why do styles disappear after the shortcode?

Question

css

Hello! Help, please understand the issue.
I made a simple shortcode for displaying an image and text next to it (advertising). Enclosed everything in a DIV and added styles. After adding the shortcode to the text, the styles are lost. The paragraph following the shortcode is rendered clumsily. What could be the problem? I broke my whole head already .....
Below are the screenshots of the shortcode, as well as what is displayed and the screen of the inspector
