How to make a Question Mark Cursor with CSS

Use cursor: help.

.yourElement {
    cursor: help;
}

Example:

<style>
    .myElement {
        background: #eee;
        border: 1px dotted #ccc;
        cursor: help;
        padding: 5px;
    }
</style>

<span class="myElement" title="More info">info</span>

Output (hover over the “info” text):
