| 11 The `core-tooltip` element creates a hover tooltip centered for the content | |
| 12 it contains. It can be positioned on the top|bottom|left|right of content using | |
| 13 the `position` attribute. | |
| 14 | |
| 15 To include HTML in the tooltip, include the `tip` attribute on the relevant | |
| 16 content. | |
| 17 | |
| 18 <b>Example</b>: | |
| 19 | |
| 20 <core-tooltip label="I'm a tooltip"> | |
| 21 <span>Hover over me.</span> | |
| 22 </core-tooltip> | |
| 23 | |
| 24 <b>Example</b> - positioning the tooltip to the right: | |
| 25 | |
| 26 <core-tooltip label="I'm a tooltip to the right" position="right"> | |
| 27 <polymer-ui-icon-button icon="drawer"></polymer-ui-icon-button> | |
| 28 </core-tooltip> | |
| 29 | |
| 30 <b>Example</b> - no arrow and showing by default: | |
| 31 | |
| 32 <core-tooltip label="Tooltip with no arrow and always on" noarrow show> | |
| 33 <img src="image.jpg"> | |
| 34 </core-tooltip> | |
| 35 | |
| 36 <b>Example</b> - rich tooltip using the `tip` attribute: | |
| 37 | |
| 38 <core-tooltip> | |
| 39 <div>Example of a rich information tooltip</div> | |
| 40 <div tip> | |
| 41 <img src="profile.jpg">Foo <b>Bar</b> - <a href="#">@baz</a> | |
| 42 </div> | |
| 43 </core-tooltip> | |
