I am doing a group project where we are trying to replicate this website and I have been assigned this section: 
I have everything laid out with flexbox but for some reason can't get the text centered for the section on the right. This is what I have got so far: 
I tried using justify-content: center and align-items: center but nothing happens to the text. How do I align everything in the center?
Here is all my code in a codepen: https://codepen.io/caseycling/pen/VwmExMY
Here is my HTML:
'<body>
<div class="container">
  <div class="ten-img">
    <h1>10</h1>
  </div>
  <div class="yrs-exp">
    <h2>Years Of Experience</h2>
    <p>

      creating unique software for you.
    </p>
    <button>Get In Touch</button>
  </div>
  <div class="deats-cont">
    <div class="deat" id="deat-1">
      <h1>2K</h1>
      <p>Apps developed</p>
    </div>
    <div class="deat" id="deat-2">
      <h1>40</h1>
      <p>Consultants</p>
    </div>
    <div class="deat" id="deat-3">
      <h1>12</h1>
      <p>Awards</p>
    </div>
    <div class="deat" id="deat-4">
      <h1>160</h1>
      <p>Employees</p>
    </div>
  </div>
</div>
<div class="clients">
  <a
    ><img
      src="https://ld-wt73.template-help.com/wt_prod-18959/images/clients-9-270x117.png"
      alt="mittos"
  /></a>
