How to align image and text side by side? HTML CSS flexible box

Question

The text is now aligned below the image. I want the text to be vertically aligned next to the image. I tried adding flex-direction: column and justify-content: center but that didn't work. I also tried float but that didn't work either. I can't figure out how to align text and image side by side. How can I align them side by side? Are there any errors in my code?

.whoweare {
  padding: 80px 0px 50px;
  background-color: #000000;
}

.whoweare #whoweareimg {
  width: 100%;
  min-width: 200px;
}

.whoweare .content {
  -webkit-display: flex;
  display: flex;
  flex-wrap: wrap;
  /* flex-direction: column; */
  /* justify-content: center; */
}

.whoweare .content .box {
  /* padding:5px;
flex:0 0 100%;
max-width: 100%; */
  padding: 5px;
  flex: 0 0 100%;
  max-width: 100%;
}

.whoweare .content #whoweareimg {
  width: 50%;
  -webkit-transform: rotateY(180deg);
  transform: rotateY(180deg);
  padding: 30px;
}

.whoweare .content h2 {
  font-size: 50px;
  font-weight: 500;
  margin: 20px;
  color: #ffffff;
  padding: 0px 0px 20px;

There seems to be a problem with your HTML code because one of the <div class="box text wow slideInRight"> is nested inside another <div class="box text wow slideInRight">, but anyway, here is the code I came up with to solve your problem.

The idea is.whoweare .content .box:first-child is your elastic container, its two child elements (<div class="item wow bounceInUp">and another <div class="box wow text slideInRight">) will be aligned side by side.

.whoweare {
  padding: 80px 0px 50px;
  background-color: #000000;
}

.whoweare #whoweareimg {
  width: 100%;
  min-width: 200px;
}

.whoweare .content .box {
  padding: 5px;
  max-width: 100%;
}

.whoweare .content .box:first-child {
  display: flex;
}

.whoweare .content #whoweareimg {
  width: 50%;
  -webkit-transform: rotateY(180deg);
  transform: rotateY(180deg);
  padding: 30px;
}

.whoweare .content h2 {
  font-size: 50px;
  font-weight: 500;
  margin: 20px;
  color: #ffffff;
  padding: 0px 0px 20px;
}

.whoweare .content p {
  font-size: 20px;
  line-height: 50px;
  color: #ffffff;
  margin: 20px;
  padding: 0px 0px 20px;
  font-family: 'Open Sans', sans-serif;
}
