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: 
**FIX FOR ME IN LOCAL CSS FILE:** I had to right click on each file and try to "Edit with Dreamweaver" until I found the one that really was behind the crashing on start up. I got the crash on index and a specifc css file (local).

I;m using Bootstrap 3. Works fine on my laptop running wamp, but not on my main PC using IIS7. I tried all the other registry cleaning and cache cleaning techniques, but no go until I removed this one piece of code from the local css file.

Hope it helps someone else.

This I removed this section of a css file:

```
@media (min-width: @screen-sm-min) { 
    .featured-box{
        margin-top:5px;
    }
}

```
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/
