Html
<div ng-controller="AppCtrl" ng-cloak="" class="tooltipdemoBasicUsage" ng-app="MyApp">
<md-content layout-padding="">
<md-button class="md-fab md-fab-top-right right" aria-label="Photos">
<md-icon md-svg-src="img/icons/ic_photo_24px.svg" style="width: 24px; height: 24px;"></md-icon>

</div>
CSS:
.tooltipdemoBasicUsage md-toolbar .md-toolbar-tools .md-button, .tooltipdemoBasicUsage md-toolbar .md-toolbar-tools .md-button:hover {
box-shadow: none;
border: none;
transform: none;
-webkit-transform: none; }
.tooltipdemoBasicUsage .left {

Answer 1

Adding this CSS seems to work in your case (with the <br>s):
md-tooltip .md-content {
height: auto;
}
I'm not sure why Angular-Material hard-coded the height to 22px. You'll need to check whether this change breaks other tooltips.
Or you can apply it specifically to this use case only by giving it a class, e.g. tt-multiline, so you can target it in CSS:
md-tooltip.tt-multiline .md-content {
height: auto;
}
Edit: Starting from Angular-Material 1.1, some class names have changed to start with a underscore.
In this case use
md-tooltip ._md-content {
height: auto;
}
and for specific class
md-tooltip.tt-multiline ._md-content {
height: auto;
}

Since angular-material version >1.1.2 you can simply override .md-tooltip class: (JsFiddle)
.md-tooltip {
height: auto;
}
And if you want to style a particular tooltip, add a custom class to md-tooltip element:
(jsFiddle)
HTML
<md-tooltip class="tooltip-multiline">
I'm a multiline <br/> tooltip
</md-tooltip>
CSS
.tooltip-multiline {
height: auto;
}
both cases tested in angular-material 1.1.2, 1.1.3 and 1.1.4 versions

Set the max-with's below to what ever you need. Now it will do automatic line breaks or put a <br/>
into it.
md-tooltip .md-content {
height: auto !important;
max-width: 200px !important;
font-size: 13px !important;
}
md-tooltip {
height: auto !important;
max-width: 200px !important;
font-size: 13px !important;
overflow: visible !important;
white-space: normal !important;
}
md-tooltip ._md-content {
height: auto !important;
max-width: 200px !important;
font-size: 13px !important;
}

You can view the styling for md-tooltip (v0.11.4) here: https://cdnjs.cloudflare.com/ajax/libs/angular-material/0.11.4/angular-material.css
My own overwrites to the material design styling to allow nice looking multi-line tooltips:
md-tooltip {
font-family: Roboto, 'Helvetica Neue', sans-serif;
.md-background {
border-radius: inherit;
}
.md-content {
height: auto;
width: 400px;
max-width: 400px;
padding: 8px;
white-space: initial;
}
}
#media screen and (min-width: 600px) {
md-tooltip .md-content {
font-size: 14px;
height: auto;
width: 300px;
padding: 8px;
max-width: 300px;
}
}

Answer 5

Or you can use white-space: pre-line; in the custom class of your md tooltip. :)

After a while searching for a solution FROM A VARIABLE CONTENT:
.ts
public matTooltipContent: string = 'Line 1 comment\nLine 2 comment\nLine 3 comment'
.html
<button mat-icon-button aria-hidden="false" class="material-icons-outlined"
[matTooltip]="matTooltipContent"
matTooltipClass="allow-cr"
(click)="onInfoButtonClicked($event)">
<mat-icon >help_outlined</mat-icon>
</button>
.css
.allow-cr {
white-space: pre;
}
See stackblitz example

Answer 7

I am using angular_material 1.1.8, for me single answer didn't work, a combination did.
html
<md-tooltip class="tooltip-multiline">Years ago, when I was backpacking...</md-tooltip>
css
.tooltip-multiline {
height: auto;
white-space: pre-line;
max-width:300px;
line-height: 14px; /*optional*/
font-weight:200;/*optional*/
letter-spacing: 0.5px; /*optional*/
font-size:11px;/*optional*/
}
Hope it helps..

angular material tool tip is warping all content in div so this its working
<md-tooltip class="tooltip-multiline" md-direction="left">
This is tooltip
</md-tooltip>
.tooltip-multiline div{
height: auto;
}
