I want use +1 for increase number of votes in system , te idea it´s add 1 by each user i use this code :

```
<a onclick="increase_n(1)" href="#">Add 1</a> 

<script>
function increase_n(size)
{
var size_ini=15;
var size_increase=size_ini+(++size);
$(".content").css("font-size",""+size_increase+"px")
}
</script>

```

I don´t know how auto increase the number when i go and do click other time , the idea it´s increase the number in each click , in one click give 11 other click give 12 other 13 , etc
