I have a multiline plain text field:
<td valign="top" width="350px" class="ms-formbody">
<div class="dffs_tdWrap">
<!-- FieldName="sbOrgs"
FieldInternalName="sbOrgs"
FieldType="SPFieldNote"
-->
<span dir="none">
<textarea rows="6" cols="20" id="sbOrgs_c614fe98-13b1-436c-9a54-624861a97862_$TextField" title="sbOrgs" class="ms-long"></textarea><br>
</span></div></td>
When I type custom css
textarea:focus{
background-color:#FFFBCC;
}
in the Field CSS tab, after saving nothing is changed and when I open again setup dialog, my css is absent.
When I type my css in the Misc section — all is right.
