A system to convert html page to a prettier one as a web service : <p>As the title is too vague to understand, let me explain.</p>

<p>This is a webpage of petal laws in Japan.<br>
<a href="http://law.e-gov.go.jp/htmldata/M40/M40HO045.html" rel="nofollow">http://law.e-gov.go.jp/htmldata/M40/M40HO045.html</a></p>

<p>This look gray, drab and not interesting, right? So I'd like to set up a web service to do a little job to convert this to "better" looking one. More colors, more indentations and even a feature that a user hovers the cursor over a word and sees a pop up saying the definition of the word. But the issue is, I don't know much about technology to achieve this goal.</p>

<ol>
<li>Is there a technology to achieve this.</li>
<li>If any, what is it called?</li>
</ol>

<p>Any help would be appreciated. Thanks.</p>
