Actually you can use wp_enqueue_style for this, by combining with the style_loader_tag filter. E.g.:<br><br>add_filter(&#39;style_loader_tag&#39;, &#39;suffusion_filter_rounded_corners_css&#39;, 10, 2);<br>function suffusion_filter_rounded_corners_css($css_html_tag, $handle) {<br>
    if ($handle == &#39;suffusion-rounded&#39;) {<br>        return &quot;&lt;!--[if !IE]&gt;--&gt;&quot;.$css_html_tag.&quot;&lt;!--&lt;![endif]--&gt;\n&lt;!--[if gt IE 8]&gt;&quot;.$css_html_tag.&quot;&lt;![endif]--&gt;\n&quot;;<br>
    }<br>    return $css_html_tag;<br>}<br><br><br><div class="gmail_quote">On Wed, May 16, 2012 at 8:14 AM, .: chris :. <span dir="ltr">&lt;<a href="mailto:chris@jazzsequence.com" target="_blank">chris@jazzsequence.com</a>&gt;</span> wrote:<br>
