Thanks Andy that worked but I should have made myself clearer I want to be able to add the text in admin style properties basic options so its not the same text on each style need the option of adding text or logo in the admin section like my example below. I have made this in the development...
I just replaced this in node_list_category template and works fine for me. it is right in the begining of the template.
<xf:macro name="depth1" arg-node="!" arg-extras="!" arg-children="!" arg-childExtras="!" arg-depth="1">
<div class="block block--category block--category{$node.node_id}">...
