title: What exactly does the flex tag mean?
body: <p>I was wondering what the flex tag meant in css. Ive used it for some positioning a few days ago but I was wondering what it exactly does. </p>
  
  <p>Ive googled some explanations and camge to sites like W3 and W3schools but not more than that. And everything there was the same. </p>
  
  <blockquote>
    <p>Initial its: 1 0 auto</p>
  </blockquote>
  
  <p>Most of the explanation is undersandable but I cant seem to find out what the "1 0 auto" means. As is now I still think its an boolean 1 = yes / 0 = no but can someone explain what the flex tag actually does? </p>
  
  <p>Ive used it in CSS like this</p>
  
  <pre><code>.flextest {
     width: 100%;
     height: 100%;
     display: flex;               &lt;---
     align-items: center;
     position: relative;
     top: -81px;
  }
  </code></pre>
  
  <p>This works for my problem but im not sure what I did here.</p>
  
  <p>This was not a question here. So either this will be hated or this will be a good addition for the community. So I am sorry if this does not belong here. I saw it as an programming question.</p>
