WRT applications are very slow -- what should I avoid to develop a responsive app

[suhansaha]

1. It seems the performance of the widget varies immensely depending on the usage of different CSS tags.
Couple of days back I created one interface with custom top and bottom menu bar using postion:fixed.
After that the app became very slow.
Is there any comprehensive study document on the usage of CSS apart from the ones already available in the forum nokia.

2. Which of the below is more efficient:

1. Include multiple no of CSS files
2. Put all the css declarations in a single file
3. Adding multiple classes to a single element
4. Adding all the css styles in a single class

Hi there, suhansaha!

The postion:fixed maybe something causing browser slow-down on drawing operations.

Please check this recent wiki-article thru, it handles about performance and offers some tips you might want to test.
