stop div resizing parent div using css

Here is a demo, but you should really explain: do you want the height to be variable ?

jsFiddle demo

edited CSS (only changed elements):

#Blog1 .post{
    border:1px solid #000000;
    margin:3px;
    text-align:center;
    position: relative;
    display:block;         /**/
    float:left;            /**/
    overflow:hidden;       /**/
    padding-bottom:24px;   /**/
}
.post .post-info span{
    position:absolute;     /**/
    word-wrap:break-word;
} 

P.S: this question associates me to an old answer of mine :)
