my expanding box starts open i want it to start closed

[deansaddigh]

Heres the function

 

$(function()
{

$("#mostrar").click(function(event) {
event.preventDefault();
$("#caja").slideToggle();
});

$("#caja a").click(function(event) {
event.preventDefault();
$("#caja").slideUp();
});
});

 

Does anyone know how to make it start closed

Sorry it actually does start closed i was missing a bit of css styling.
