title: How to use custom CSS in an Odoo 10 POS addon
body: <p>My custom CSS isn't being loaded when I launch the POS app, but it's loaded into web.assets_backend.1.css in the dashboard. My custom Javascript is being loaded correctly. Is this the correct way to load the CSS? Thanks for your help.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  &lt;odoo&gt;
      &lt;data&gt;
          &lt;template id="assets_backend" inherit_id="web.assets_backend" name="donation_assets_backend"&gt;
              &lt;xpath expr="." position="inside"&gt;
                  &lt;link rel="stylesheet" href="/donation/static/src/css/donation.css" /&gt;
  
                  &lt;script type="text/javascript" src="/donation/static/src/js/donation.js"&gt;&lt;/script&gt;
                  &lt;script type="text/javascript" src="/donation/static/src/js/jquery.sglide.js"&gt;&lt;/script&gt;
                  &lt;script type="text/javascript" src="/donation/static/src/js/sGlide.js"&gt;&lt;/script&gt;
                  &lt;script type="text/javascript" src="/donation/static/src/js/donation_frontend.js"&gt;&lt;/script&gt;
              &lt;/xpath&gt;
          &lt;/template&gt;
      &lt;/data&gt;
  &lt;/odoo&gt;
