Question: I want to implement layering of screens when transitioning from one screen to another.

Requirement:

i> There is a screen with a button.

ii> When the user clicks on the button , the next screen is displayed in the following manner.

It should move up from down & place on top of the existing screen.
On iPhone , technically its known as implementing the **present model view controller**

I am aware of moving screens left & right , but is there already available API for implementing what I have mentioned.

Any inputs/sample code for implementing the same will be useful.

Warm Regards,

CB

Answer: 
Great, this post helped me solve my problems of crashed on a specific file in Dreamweaver CS5.
It's indeed the external font that crashes DW.

I found an easy fix, omit the protocol part and it works:

```
<link href="//fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet" type="text/css">

```

and **NOT**

```
<link href="http//fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet" type="text/css">

```
First I put the comment tag around the jQuery link to see that it was as suggested above and no it was not.

The problem started after I started the media query in the CSS. I left it fragmented [I had not finished]

Here is the fragment with comment tags around it to disable it.

```
    /*
@media screen and (max-width:
*/

```

The comment tags for html are different than the css ones they look like this: `<!-- [line of html code] -->`

For css use: `/* [line of CSS code] */`

Using the comment tags to disable suspect code is more handy than just deleting things.

Hope that helps somone/
