title: How to give an space between figures on subfigure latex ambient?
body: <p>I am using the command \begin{subfigure}...\end{subfigure} to insert three pictures side by side. But I would like to know how to give an space between then, since they are too close each other.</p>
  
  <pre><code>\begin{figure}
      \begin{subfigure}
         here's the first image
      \end{subfigure}
      \begin{subfigure}
         here's the second image
      \end{subfigure}

         here's the third image
