How to set a margin on a Array

[kpowers4]

I have this code below that produces an array.  How do i write a line of code that allows me to set its margin or alignment?

 

foreach($food_categories  as $key => $subarray)        #20

{

  echo "<h3>$key</h3>";

    echo "<ul>";

    foreach($subarray as $type)

    {

      echo "<input type='radio' name='interest'

                    value='$type'><b>$type</b><br>\n";

    }

    echo "</ul>";

}

That's not an array, and there are no arrays in HTML.

 

Show us the HTML output and tell us which element you want to add the margin to.
