Conflicts between Custom theme CSS and Liferay CSS

[manni java, módosítva 9 év-val korábban]

I am trying to customize the Liferay UI by using custom theme using base as as "_Styled" theme.

I have my own css files which I coped to _diff/css folder of theme and imported them "custom.css" file .However its breaking the presentation of liferay.In my custom CSS I have styles defined for all the standard tags like body,div etc which is impacting the liferay UI too.

How can I resolve this conflict? Thanks in advance!

You assign portlet-specific classes to your html entities (i.e. through the liferay-portlet.xml file). That way you can narrow the CSS selectors so the styles only apply to your elements.

Thanks for reply.I am adding all these portlets dynamically ,by specifying them in portal_normal.vm file. I do not have my custom portlet and hence do not have liferay-portlet.xml.

How can I specify styles for these kind of portlets?
