title: How to make in bootstrap a input with only 1 character width?
body: <p>Im making a Soccer Bet app. </p>
  
  <p>I'm using React and bootstrap and now I'm stuck in a apparently simple problem. </p>
  
  <p>I want to make a input for the bets (in soccer the matches always are lower than 3 digits). How can I make a input with a fixed size of 2 characters in bootstrap? </p>
  
  <p>My screen, for example, will have home and away teams, and 2 inputs with the desirable bet of the user like: </p>
  
  <p>BRAZIL [] x [] GERMANY. </p>
  
  <p>These inputs needs to have a fixed size of 2. </p>
  
  <p>Thanks</p>
