Abstract

A method receives a request at a server from a browser for at least one markup language page. The method can then determine which CSS classes are used with the requested markup language page using a usage map. Then, the method loads the markup language page and loads only the CSS classes that are used with the markup language page to the browser.

Claims

1. A method comprising:

receiving a request at a server from a browser for at least one markup language page;

determining which cascading style sheet (CSS) classes are used with said markup language page;

loading said markup language page to said browser; and

loading only CSS classes that are used with said markup language page to said browser to allow said browser to apply said CSS classes to viewable objects within said markup language page and to display said markup language page.

2. The method according to claim 1, wherein said loading of said CSS classes further comprises loading only one instance of each CSS class.

3. The method according to claim 1, wherein each CSS class comprises at least one property and said loading of said CSS classes further comprises loading only one instance of each said property.

4. The method according to claim 1, wherein said determining comprises referencing a page-class file comprising a list of CSS classes associated with said markup language page.

5. The method according to claim 1, wherein all of said CSS classes that are used with said markup language page are loaded to said browser using a single load request from said browser.

6. A method comprising:

receiving a request at a server from a browser for at least one markup language page;

determining which cascading style sheet (CSS) classes are used with said markup language page;

logging duplicate CSS classes that have the same name and the same properties;

logging homonym CSS classes that have the same names but different properties;

logging synonym CSS classes that have the same properties but different names;

loading said markup language page to said browser; and

loading only CSS classes that are used with said markup language page to said browser to allow said browser to apply said CSS classes to viewable objects within said markup language page and to display said markup language page.

7. The method according to claim 6, wherein said loading of said CSS classes further comprises loading only one instance of each CSS class.

8. The method according to claim 6, wherein each CSS class comprises at least one property and said loading of said CSS classes further comprises loading only one instance of each said property.

9. The method according to claim 6, wherein said determining comprises referencing a page-class file comprising a list of CSS classes associated with said markup language page.

10. The method according to claim 6, wherein all of said CSS classes that are used with said markup language page are loaded to said browser using a single load request from said browser.

11. A method comprising:

before receiving a request for a markup language page, processing cascading style sheet (CSS) classes used with markup language pages in a process comprising;

logging duplicate CSS classes that have the same name and the same properties;

logging homonym CSS classes that have the same names but different properties;

logging synonym CSS classes that have the same properties but different names;

logging unused CSS classes that are not used by any markup language page; and

creating a page-class definition file that identifies CSS classes used by each said markup language page;

receiving said request at a server from a browser for at least one said markup language page;

determining which CSS classes are used with said markup language page using said page-class definition file;

loading said markup language page to said browser; and

loading only CSS classes that are used with said markup language page to said browser to allow said browser to apply said CSS classes to viewable objects within said markup language page and to display said markup language page.

12. The method according to claim 11, wherein said loading of said CSS classes further comprises loading only one instance of each CSS class.

13. The method according to claim 11, wherein each CSS class comprises at least one property and said loading of said CSS classes further comprises loading only one instance of each said property.

14. The method according to claim 11, wherein all of said CSS classes that are used with said markup language page are loaded to said browser using a single load request from said browser.

15. The method according to claim 11, wherein said CSS classes provide formatting information for said markup language page.

16. A computer program product comprising:

a computer-usable data carrier storing instructions that, when executed by a computer, cause the computer to perform a method comprising;

receiving a request at a server from a browser for at least one markup language page;

determining which cascading style sheet (CSS) classes are used with said markup language page;

loading said markup language page to said browser; and

loading only CSS classes that are used with said markup language page to said browser to allow said browser to apply said CSS classes to viewable objects within said markup language page and to display said markup language page.

17. The computer program product according to claim 16, wherein said loading of said CSS classes further comprises loading only one instance of each CSS class.

18. The computer program product according to claim 16, wherein each CSS class comprises at least one property and said loading of said CSS classes further comprises loading only one instance of each said property.

19. The computer program product according to claim 16, wherein said determining comprises referencing a page-class file comprising a list of CSS classes associated with said markup language page.

20. The computer program product according to claim 16, wherein all of said CSS classes that are used with said markup language page are loaded to said browser using a single load request from said browser.
