The <code>pad</code> descriptor allows you to specify a fixed-width counter style so that any representations shorter than the pad width are padded with your chosen symbol.</p> <p>Here's an example of using the <code>pad</code> descriptor. </p> <script src="/common/js/codemirror/lib/codemirror.js"></script> <script src="/common/js/codemirror/mode/css/css.js"></script> <div class="code-only"> <textarea id="example1" autocomplete="off" spellcheck="false">@counter-style numeric-padded {

 symbols: "0" "1" "2" "3" "4" "5" "6" "7" "8" "9";
 pad: 3 "0";
} 

/* Now we can use the above style by referring to its name */ 
ol { 
 list-style-type: numeric-padded;
}</textarea> </div> <script> var exampleCode1 = CodeMirror.fromTextArea(document.getElementById("example1"), { mode: "text/css", tabMode: "indent", styleActiveLine: false, lineNumbers: false, lineWrapping: true, theme: "q-dark" }); </script> <p>If your browser supports the <a href="/css/at-rules/css_counter-style_at-rule.cfm"><code>@counter-style</code></a> at-rule, the above code could result in a list that looks something like this:</p> <figure> <img class="img-responsive" src="/pix/stock/css_counter-style_pad_zeros.gif" alt="Example of an ordered list styled with padding."> <figcaption> An ordered list styled with padding applied to three digits wide. </figcaption> </figure> <h2>Possible Values</h2> <p>The <code>pad</code> descriptor accepts the following values.</p> <script src="/common/js/codemirror/mode/text/css/text/css.js"></script> <div class="code-only"> <textarea id="example2" autocomplete="off" spellcheck="false"><integer> && <symbol></textarea> </div> <script> var exampleCode2 = CodeMirror.fromTextArea(document.getElementById("example2"), { mode: "text/css", tabMode: "indent", styleActiveLine: false, lineNumbers: false, lineWrapping: true, theme: "q-dark" }); </script> <p>The <a href="/css/data_types/css_integer_data_type.cfm"><var class="css-data-type">integer</var></a> specifies a minimum length that all counter representations must reach. This must be a non-negative value.</p> <p>The <var class="css-data-type">symbol</var> is used to pad any representation where its length is less than the specified integer. </p> <p>A common use case is to pad counters with zeros so that <code>1</code> becomes <code>01</code> or <code>001</code> or however many zeros you need to pad it with, however, it can be used to pad it with any symbol.</p>
