HTML tags in views field label. Is it possible?
Uncheck create label

Click on rewrite results, check mark override out and put:

  &lt;span class="views-label views-label-price"&gt;Price: &lt;span&gt;-10%&lt;/span&gt;&lt;/span&gt;
  &lt;span class="field-content"&gt;{{ field_price }}&lt;/span&gt;


I'm not 100% that it's {{ field_price }}, but you can click on replacement patterns to see the pattern name.
