How can I put my text and image in the middle of a div?

Question

I have 4 different rows of two columns and I have a picture on one column and text on the other. As the text and images are different sized I want them to be in the middle vertically.

This is my code for one of the columns and CSS for that div

.col2 {
  float: left;
  width: 46%;
  padding: 2%;
  text-align: center;
  position: relative;
  justify-content: center;
  height: 300px;
}

<div class="col2">
        <img src="images/freelance.png" alt="three people watching a presentation">
</div>
<div class="col2">
    <h2>Work as a Freelancer</h2>

    <div class="book">
        <a class="booked" href="#" target="_blank"><p><b>Book 14th March 6pm</b></p></a>
    </div>
</div>

This is the before with my code

This is with @N3v4da Stone 's changes

Answer 1

N3v4da's explanation does work, however I will try and go into some more detail.

Wrapper div uses flexbox to display elements in a row.

align-items: center; centers items vertically along the flex row (this means that the text is centered with the image)

justify-content: space-between puts the img and div elements to opposite sides of the wrapper div.

gap: 20px ensures there is always a 20px gap in between the img and div

.wrapper {
  display: flex;
  align-items: center;
  justify-content: space-between;
  gap: 20px;
  
  background-color: lightblue;
}

.wrapper img {
  width: 300px;
  height: 300px;
}

<div class="wrapper">

    </div>
  </div>
</div>

Make sure you remove any CSS that may interfere with this code, this might be why N3v4da's version didn't work. This is what my solution does

Answer 2

Use a container and flexbox CSS for wrap your col. Maybe like this if isn't correct, provide an image that you want.

.flex-container {
        display: flex;
        flex-flow: row wrap;
        justify-content: space-between;
        align-items: center;
     }

   .col2 {
      width: 46%;
      padding: 2%;
      text-align: center;
  }

 <div class="flex-container">
       <div class="col2">
