Bitrix Site Manager and Bitrix24 use and support the following technologies.


The system places no restrictions on templates developed with HTML/XHTML.


The system unconditionally supports the use of JavaScript in the site templates, menus and pages.


This technology is widely used in the Control Panel and Components 2.0 to speed up the system response and decrease server-to-client data traffic. The system places no restrictions on using AJAX in the public section.


The design of each site template can be controlled via separate CSS files. Analogously, separate style sheets can be used with public components as well as module templates (e.g. forum, helpdesk, polls). The Control Panel features the use of visual themes: users can create their own custom visual themes through the cascading style sheets.


The system has limited support for the Macromedia (now Adobe) Flash technology. Flash plug-ins can be used in the following ways:

  • as a part of the site template design;
  • as advertising banners;
  • as user input controls deliberately designed to interact with the system.


The system supports RSS versions 0.92 and 2.0. In the core, RSS is used to exchange information between the Information Blocks and Blogs modules.


The system uses the CSV standard to exchange information between the Information Blocks module and other systems.

Browser support

Bitrix Site Manager and Bitrix24 were developed to support the most popular browsers (Internet Explorer 11.0 and higher). The Control Panel is optimized for the maximum performance with them. The public section appearance is browser-independent.

Known problems

  • The visual editor behaviour may somewhat disagree in different browsers (Internet Explorer and FireFox).
  • Some API functions and class methods may produce HTML code that do not fully conform with the XHTML standard, and potentially may not pass the W3C validation.
