  <li><p><strong>Change the size of check boxes and radio buttons in Shiny?</strong></p></li>
  <li><p><strong>Change the vertical spacing between the boxes/buttons?</strong></p></li>
  </ol>
  
  <p>I'm brand new to Shiny (day 1), so I'm sorry if this seems obvious.</p>

  <p>My Code so far: </p>
  
  <pre><code>ui &lt;- fluidPage(
  
    sidebarPanel(width = 3,
  
      fluidRow(
        column(6,offset=0,
          div(style = "font-size: 8px;",      
            selectInput(inputId = "size",
              label = "Tree Size",
              choices = c("All","Canopy","Subcanopy","Small"),
              selected = "All"),
          )
        ),
  
        column(6,offset=0,
          div(style = "font-size: 8px;padding:0px;",
            checkboxGroupInput(inputId = "labels",
               label = "Labels",
