How to solve the layout problem when inserting a calculator on a wordpress site with a shortcode?

Question

css

Hello
Here, I made my first wordpress plugin, inserted its shortcode call into the page. The calculator form was included in the entry-content block of the site. With screen resolutions from 1616 * 852 to 976 * 852, the layout does not move around. At resolutions below 907 * 852, the calculator form seems to fall out of the flow. Can you tell me where to look for a solution?

Answer 1

Is the css of the block obvious?
