CSS classDescription


Styles the entire Tooltip.



This example creates a Tooltip for a button.

<div class="tooltipAnchor" data-win-control="WinJS.UI.Tooltip" 
    data-win-options="{innerHTML: 'Go to the next page'}">

By default, div elements have a display setting of block. When using a div element to host the Tooltip, set its display property to inline-block.

    display: inline-block;

You can also use another element as the contents of your Tooltip. To use another element, set the contentElement property to the ID of the element you want to use. Here's an example:

<div data-win-control="WinJS.UI.Tooltip" 
    data-win-options="{infotip: true, contentElement: myContentElement}">
    <a href="somelink.htm">Box Office No. 1</a>
<div style="display: none;">
    <!--Here is the content element. It's inside a hidden container so that 
        it's invisible to the user until the tooltip displays it.-->
    <div id="myContentElement">
        <div id="myContentElement_rating">
            <div data-win-control="WinJS.UI.Rating" 
                class="win-small movieRating" 
                data-win-options="{userRating: 3}"></div>
        <div id="myContentElement_description">
                You can provide any HTML element as content, even one that has contains
                Windows Library for JavaScript controls. The tooltip control add the 
                the element as a child of the tooltip container 
                and blocks interaction events on that element.</p>
        <div id="myContentElement_picture">

When you run the code, it displays the content element as the tooltip.

A tooltip that contains images and a Windows Library for JavaScript control.

Here are the CSS styles that accompany this example:

    display: -ms-grid;
    width: 350px;
    -ms-grid-rows: 40px auto;
    -ms-grid-row-align: start;
    padding: 10px;

    -ms-grid-column: 1;

    background-image: url("../images/SauceCaramel.png");
    background-position: center top;
