Table scroll shadows - Script Codes HTML Codes

<!DOCTYPE html>
<html >
<head> <meta charset="UTF-8"> <title>Table scroll shadows</title> <link rel="stylesheet" href="css/style.css">
</head>
<body> <h1>Table scroll shadows</h1>
<div class="wrapper"> <p>Here is a small workaround for indicating if a table is wider than its surrounding (scrollable) container. This is handy if a browser isn't showing scrollbars by default, i.e. on mobile devices.</p> <p>Right now there are no reliable ways to achieve this effect in CSS, so we need JS.</p> <p>Tables receive inner shadows on the sides which are not (or nearly) scrolled to the end. The shadow width is defined in the CSS class 'table-shadow'. The scroll distance needed to show the shadow in full opacity is also inherited by this value.</p> <p>It doesn't matter which size the table has:</p> <div class="table-wrapper"> <table style="width:500px" class="table"> <tr> <td>fooooooooooooooooooooooooooooooo</td> <td>fooooooooooooooooooooooooooooooo</td> <td>fooooooooooooooooooooooooooooooo</td> </tr> <tr> <td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaar</td> <td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaar</td> <td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaar</td> </tr> <tr> <td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaz</td> <td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaz</td> <td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaz</td> </tr> </table> </div> <div class="table-wrapper" style="width:300px"> <table class="table"> <tr><td>fooooooooooooooooooooooooooooooooooooooooooo</td></tr> <tr><td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaar</td></tr> <tr><td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaz</td></tr> </table> </div> <p>If the table is smaller than the wrapper, there is no shadow shown. The shadow elements are already there, so there is no problem with dynamically filling the table.*</p> <div class="table-wrapper" style="width:300px"> <table class="table"> <tr><td>fooooooooooooooooooooooooooooooo</td></tr> <tr><td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaar</td></tr> <tr><td>baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaz</td></tr> </table> </div> <p>*I do not claim for this to be bug free. Example: Right now, after inserting content to the table when it's already rendered, the shadow won't update	until you scroll.</p> <p>Also, this could easily be done in Vanilla JS (right now it's dependent on jQuery) and isn't really optimized in any way (although it should work cross browser).</p> <small>P.S.: Isn't that a beautiful gradient in the background?</small> <footer><em>Something to say?
