The input search field for the audit portlet needs to be updated to match lexicon markup and look and feel. See https://clayui.com/docs/components/toolbars/management-toolbar.html for more details.

The body content fields need to match lexicon's markup and look and feel as well.

Steps to reproduce:

• Navigate to Control Panel > Audit

Actual result:
Search bar is styled as pre-lexicon. Body content style is pre-lexicon.
