javascript - Removing leading whitespace from indented HTML source in pre/code tags

Question

I currently have the following html within a pre-code block:

                <pre class="prettyprint"><code>
                    &lt;html&gt;
                    &lt;body&gt;

                    &lt;form name=&quot;input&quot; action=&quot;html_form_action.asp&quot; method=&quot;get&quot;&gt;
                    &lt;input type=&quot;radio&quot; name=&quot;sex&quot; value=&quot;male&quot;&gt;Male&lt;br&gt;
                    &lt;input type=&quot;radio&quot; name=&quot;sex&quot; value=&quot;female&quot;&gt;Female&lt;br&gt;
                    &lt;input type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
                    &lt;/form&gt; 

                    &lt;p&gt;If you click the &quot;Submit&quot; button, the form-data will be sent to a page called &quot;html_form_action.asp&quot;.&lt;/p&gt;

                    &lt;/body&gt;
                    &lt;/html&gt;
                </code></pre>

It is indented within the html source for better structure within the document. How can I remove the leading whitespace? Through the use of javascript or is there a more simple method.

Answer 1

The question asks if there's a JavaScript solution or a simpler method for removing leading whitespace. There's a simpler method:

CSS

pre, code {
    white-space: pre-line;
}

DEMO

white-space

The white-space property is used to describe how whitespace inside the element is handled.

pre-line

Sequences of whitespace are collapsed.
