title: Change the color of a input-field when selected
body: <p>i haven't found the code yet. Maybe someone can help me?
  I want to change the border-color of a input type="text" field when it is selected. Atm the border gets blue when i click in such a field.
  I tried border-color but it didn't work. I am new to css and html. </p>
  
  <pre><code>&lt;input type="text" placeholder="Name..."&gt;
  </code></pre>
  
  <p>Thanks!</p>
  
  <p>Edit: I don't talk about the background-color! I just want to change the color of the mark around the box thats visible when the box gets selected.</p>
