Genesis does not include any conditional comments in page templates by default. Instead I highly recommend the Conditional Styles module, which comes built into the latest version of Genesis (6.x-2.2).
The Conditional Styles module allows you to add stylesheets for Internet Explorer in your subthemes info file.
How to enable Conditional Styles
- Uncomment the relevant line of code in your subthemes info file (see below)
Here is the relevant code from the default genesis_SUBTHEME. Here I have included one CC stylesheet to target IE7 or less. To use just uncomment
conditional-stylesheets[if lt IE 7][all] = css/ie/ie-example.css and then start modifying the relevant stylesheet. You probably want to rename it form ie-example.css as this is of course, just for example.
;----------// IE Conditional Stylesheets
; Support for the Conditional Styles module. This module allows themes
; to specify conditional stylesheets in their .info file and the conditional
; comments will be automatically included at the end of the standard $styles variable.
; Install the module and then uncomment or add the required stylesheets.
; There is an example IE stylesheet are in your subthemes css/ie folder.
; Example only: see the README in the Conditional Styles module
;conditional-stylesheets[if lt IE 7][all] = css/ie/ie-example.css
If you are using an older version of Genesis (6.x-2.1 or earlier) you will need to download the Conditional Styles module and install it as a stand alone module.
