.div_job {
	width:888px;
	height:320px; /* ใส่ 	height:auto; ก็ไม่ได้ครับ */

	border: 1px double #D4D4D4;
	border-top-left-radius:1em;
	border-top-right-radius:1em;
	border-bottom-left-radius:1em;
	border-bottom-right-radius:1em;
	position:relative;
}
.div_job:hover {
	width:888px;
	height:320px;  /* ใส่ 	height:auto; ก็ไม่ได้ครับ */
	margin-bottom:5px;

	border-top-left-radius:1em;
	border-top-right-radius:1em;
	border-bottom-left-radius:1em;
	border-bottom-right-radius:1em;
	-moz-box-shadow: 0 0 5px #D8D8D8;

.div_job_head_position {
