Remove start and end border ionic-list tag in ionic 2

One way would be to add no-lines in the ion-list element like this:

<ion-list no-lines>...</ion-list> 

but that will remove the lines of the items too. So in order to remove only that line in the bottom you can add this style rule:

.md ion-list > .item:last-child, 
.md ion-list > .item-wrapper:last-child .item,
.wp ion-list > .item:last-child, 
.wp ion-list > .item-wrapper:last-child .item,
.ios ion-list > .item:last-child, 
.ios ion-list > .item-wrapper:last-child .item {
    border-bottom: none;
}

The solution that worked for me was

.list-ios>.item-block:first-child {
    border-top: none;
}
.list-ios>.item-block:last-child {
    border-bottom: none;
}

As mentioned in the comments, below is the android version

.list-md>.item-block:first-child {
    border-top: none;
}
.list-md>.item-block:last-child {
    border-bottom: none;
}
