Hello Karen,

The responsive functionality in EasyBlog has been updated to work using mobile device detection. In other words, regardless of how you resize your browser, you would not get the same mobile-ish effect. I mean, who resizes their browser to that size to view the contents of the site

If you need to test this on the browser, you could test this by adding a user agent on the browser, http://take.ms/zrusf

i also have some problem with responsive functions. I wich i chould set a class to an block, then i have the option to reach a text block with css.

Unfortunately that was not possible to add class to an block unless you modify the core file.

By the way, it should show responsive for the text block section, perhaps you can start a new thread and provide us more info regarding this? So we will check why your text block not show responsive?
