How to set up a text so that it fills a container

1

Hello, I have an issue here.
I have a container, and within it an image and some text. The image just is a part of the container, I would like that the text fills up the whole container not just one side, but even under the image. I have tried with justify-content, width, but no solution at all.
Thanks in advance,

the HTML and CSS code here:

This is the evidence on how it looks here:

This is a case where you would use float on the image to get the text to wrap around it. Also, you need to remove display: flex from the post div or the float will have no effect.

Thanks a lot, it works!
