H Pratik,

Here is the documentation an examples

If you can apply css as  this answer explain https://answers.atlassian.com/questions/99055

you can add the following 

.warningMacro{
	background: #fff;
	border-color: 1px solid #f6c342;
	border-top: 1px solid #f6c342;
	border-right: 1px solid #f6c342;
	border-bottom: 1px solid #f6c342;
	border-left: 1px solid #f6c342;
	color:   #333;
	border-radius:  3px;
	color:   #333;
	line-height:  20px;
	margin:  20px 0 0 0;
	overflow-wrap:  break-word;
	padding-bottom:  20px;
	padding-left:  60px;
	padding-right:  40px;
	padding-top:  20px;
	position:  relative;
	word-wrap:  break-word; word-break:  break-word;
}
.warningMacro:before{
	background-color:#f6c342;
	bottom: 0;content: '';
	left: 0;
	position: absolute;
	top: 0;
	width: 40px;
}
.warningMacro:after{
	content: "\f1b3";
	font-family: "Atlassian Icons";
    font-size: 16px;
    -webkit-font-smoothing: antialiased;
    font-style: normal;
    font-weight: normal;
    left: 12px;
    line-height: 1;
    margin-top: -8px;
    position: absolute;
    speak: none;
    top: 50%;
}
