I want add new class referenc-tag to point of sale
In mycss.css I have:
.referenc-tag {
color: #FFF;
background: #000;
margin-bottom:10px;
}
In xml
<template id="assets" inherit_id="point_of_sale.assets">
<xpath expr="." position="inside">
<link rel="stylesheet" href="/pos_odoo/static/src/css/mycss.css"/>
</xpath>
</template>
After add class to element and install module my element can't get style.
Your example is correct, try clear cache and add to openerp.py xml
<template id="assets" name="pos_odoo assets" inherit_id="point_of_sale.assets">
<xpath expr="." position="inside">
<link rel="stylesheet" href="/pos_odoo/static/src/css/mycss.css" />
</xpath>
</template>
to openerp.py
'data':[ 'your xml' ],
