    I prefer HTML 4.01 Strict, but soon may migrate to

  3. The HTML5 (space or no-space?) Doctype also covers everything previously so there’s no reason to not use it now.

    It triggers standards mode in IE and works correctly in all other browsers, the main reason for doctype is for validators anyway so as long as you don’t the ‘this is as yet an unfinished spec’ style of message, you’ve nothing to worry about.

      So all the old IEs need is a doctype declaration to trigger the standards mode? No matter what version of it?

    HTML4 strict is my favorite. I’ll move to in future.

      Same Doctype should work in all the browsers irrespective of the platform you are in.

      @ neha,
      The layout of your html/css/js is what determines a mobile design. There is no doctype specifically for mobile.

Posting Code

  • Use Markdown, and it will escape the code for you, like `<div class="cool">`.
  • Use triple-backticks for blocks of code.
    ``` 
    <div>
      <h1>multi-line block of code</h1>
      <span>be cool yo.</span>
    </div>
    ```
  • Otherwise, escape your code, like <code>&lt;div class="cool"&gt;</code>. Markdown is just easier though.
