Summary: This alteration will changed the default standard alerts on the inbox and display an envelope icon although I encourage to use a better image than the one I provided. Standard alerts are untouched and will display the balloon.
notes: If you have a custom navigation you may need to re-position the Icon as this was tested on a default installation.
Install: Simply upload the Icon to your /icons folder and paste the following in your EXTRA.CSS template.
Code:
.navTabs .inbox .itemCount {
background: url("@imagePath/xenforo/icons/alert_inbox.png") no-repeat scroll center transparent;
line-height: 13px;
box-shadow: none;
height: 22px;
min-width: 25px;
color: #4c4c4c;
top: -13px;}
.navTabs .inbox .itemCount .arrow { border-width: 0; }
