Semantic Elements in HTML5

A semantic element clearly describes its meaning to both the browser and the developer.

Examples of non-semantic elements: <div> and <span> - Tells nothing about its content.

Examples of semantic elements: <form>, <table>, and <img> - Clearly defines its content.

Many of existing web sites today contains HTML code like this: <div id="nav">, <div class="header">, or <div id="footer">, to indicate navigation links, header, and footer.

HTML5 offers new semantic elements to clearly define different parts of a web page:
  • <header>
  • <nav>
  • <section>
  • <article>
  • <aside>
  • <figcaption>
  • <figure>
  • <footer>

The Clickjacking attack and X-Frame-Options

Clickjacking  Clickjacking is a type of “web framing” or “UI redressing” attack. What that simply means in practice is that: 1. A user (victim) is shown an innocuous, but enticing web page (think watch online video) 2. Another web page (that generally does something important – think add friends on social network) is layered on top of the first page and set to be transparent 3. When the user thinks they are clicking on the web page they see (video), they are actually clicking on the higher layered (framed) page that is transparent There are two main ways to prevent clickjacking: 1.     Sending the proper X-Frame-Options HTTP response headers that instruct the browser to not allow framing from other domains 2.     Employing defensive code in the UI to ensure that the current frame is the most top level window Using X-Frame-Options X-Frame-Options  originally invented by Microsoft for IE8, but supported by a number ...
