My margin top does not get applied to my anchor tag

Question

My a tag with the class name of read-more is inside a Div called article text, somehow the margin top does not work, why does that happen?

When I inspected it, there seems to me a margin-top but it seems like the A tag is out of the flow of the html

Here is a link to my codepen :https://codepen.io/jerico001/pen/MWppMdG

CSS

#Article {
  display: flex;
  flex-direction: column;

Answer 1

Add display: inline-block; style to the <a> tag. Vertical margin does not work with inline elements.
