Solution 1:

You might want to use the <span> HTML tag instead of <div>.

Because each <div> is normally displayed by browsers with a line-break above and below.

Alternatively you can define how <div> should look like with CSS, but I think that's too much for the moment:

div {display: inline;}

Example with the <span> HTML element and using substr (I might be off by one or so, I assume you can fix that):

$truecol = 'hsl(0,100%,50%)';
colorSequence($seq, 5, $truecol, 3);

function colorSequence ($seq, $position, $truecol, $TFBSlength)
{
    $before = substr($seq, 0, $position);
    $color  = substr($seq, $position, $TFBSlength);
    $after  = substr($seq, $position + $TFBSLength);
    printf("%s<span style=\"color: %s;\">%s</span>%s\n",
           $before, $truecol, $color, $after);
}
