如何防止 div 容器调整大小

Question

I am using div container as a drop-able element, so I am adding buttons elements dynamically in to this div container. Div size is resizing if I am adding buttons beyond its size how to avoid this?

Note: This issue occurs in Firefox only

sample:fiddle

#divContainer{
    width:100%;
    height:40%;
    overflow:auto;
    border:1px solid;
    display:inline-block;
}
#click{
    width:100px;
    height:30px;
}
table{
    border:1px solid;
}
body{
    height:1000px;
}

//html

<button id="click">ClickME</button>
<table style="width:20%; height:30%">
    <tr>
        <td>
            <div id="divContainer">
            </div>
        </td>
    </tr>
</table>

//script

 $(function () {

        $("#click").on("click", function () {

            $("#divContainer").append($("#click").clone());
        });
    });

Answer 1

Try this..

#divcontainer
{
max-width: 40%;
max-height: 30%;
overflow:auto;
display:inline-block;
}

Since you are using table, table elements doesn't goes well in % value in different browsers, they adjust their width/height according to the content. So its better you go with max-width and min-width value (that's also in pixels), so that cross-browsers don't create any mess for your design-

Try below css code:

#divContainer{
    width:100%;
    min-height:100px;
    height:40%;
    max-height:100px;
    overflow:auto;
    border:1px solid;
    display:inline-block;
}
#click{
    width:100px;
    height:30px;
}
table{
    border:1px solid;
}
body{
    height:1000px;
}
