Question

The image below describes the issue. I am creating our comment forms. And want to create the pointer arrow in ffffff background color, and a border of 1px aaaaaa and border bottom fff so it sits comfortably on our container div

The issue I have is I can make a solid color pointer, but not sure if I can make what I want, so thought I would ask here please.

The css for the pointer is:

div.comment-reply .arrow{
border-bottom: 8px solid #888;
border-left: 6px solid transparent;
border-right: 6px solid transparent;
height: 0;
left: 30px;
line-height: 0;
position: absolute;
top: -8px;
width: 0;

}

Answer 1

@422; you can do with css like this rotate property.

css

#C{
    height:200px;
    width:200px;
    background:red;
    border:1px solid #000;
    position:relative;
    }

.arrow{
     height: 20px;
     width: 20px;
     margin-left:30px;
    margin-top:-11px;
    background:red;
    -moz-transform:rotate(45deg);
    -webkit-transform:rotate(45deg);
    border-right:1px solid #000;
    border-bottom:1px solid #000;
    position:absolute;
    bottom:-10px;
    left:20px;
}

html

<div id="C"><span class="arrow"></span></div>

you can use :after, :before instead of span.

for IE you can use ie filter

filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(SizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476)"; /* IE8 */
