Problem using jQuery to animate divs up to 100% height

Question

Hey. I use jQuery to animate divs from set height to 100% and back to a given height. This is used to show / hide text from a Wordpress message that is longer than the specified height (overflow is hidden). I cannot animate a div from a set height to 100%; instead, the div jumps to 100% of the height. He makes the animation back to her, setting the size smoothly. I cannot fix the height for the animation, because the messages will always have different heights depending on how much was written.

Here's the jQuery code:

$(document).ready(function(){

     $(".read_more").toggle(function(){
     $(this).prev(".entry").animate({height:"100%"}, {
    queue:false,
    duration:1000,
    easing: "easeOutQuart"});
     },

function(){  

        $(this).prev(".entry").animate({height:"5.9em"}, {
        queue:false,
        duration:1000,
        easing: "easeOutQuart"});

});         
});

CSS:

.entry {

     float:left;
     position:relative;
     width:870px;
     height:5.9em;
     overflow:hidden;
     padding: 0px 10px 10px 10px;
     display:block;
}

,.entry div , , . , , 100% . ?

jquery (yellow_read, invistext gray_read - , , .

    easing: "easeOutQuart"});
     $(this).children(".yellow_read").css("display","none");   
     $(this).children(".invistext").css("display","inline");
     $(this).children(".gray_read").css("display","none");
},

function(){  
    $(this).prev(".entry").animate({height:"5.9em"}, {
