Display the matched elements.
// <div class="box" style="display: none;"></div>
$('.box').show();
<div class="box" style="display: block;"></div>
Restores the display property to what it was before .hide() was called. If no previous state is stored, it tries to determine the default display for the element type (e.g., `block` for div, `inline` for span). It also correctly handles the SVG `display` attribute.
Returns: The original SR object for chaining.
