How to move an element down?

Question

css

There is a site:
autolab.pro
It is necessary to align the blocks: I

used the pseudo-class code like this:

s5__block h4:nth-child(1){
  margin-bottom: 30px;
}

It doesn't work for some reason

Answer 1

Add to CSS:
.s5__block h4 {
}
Then the title will be at least 63 pixels high. Includes two lines of text. The paragraphs below will all line up. If the title is 3 lines, then this block will move lower than the others.
