Survey project 2019

I am having trouble centering the submit button. Here’s what i have:

<div class="row">
        <div class="button">
         <input type="Submit" id="submit" value="Submit">
  margin: center;

Did I miss something somewhere? Let me know if you need more.

There is no such thing as margin: center;

I would give a fixed width to your button and give it

margin: 0 auto;

Which should center it.
