I'm editing a page and I can't change the html, only the css, but I need to change a background-image that is declared inline with !important. I've already tried to declare background-image: none !important; or change bg position until it disappear and then declare the new bg image on :before pseudo-element, but it doesn't work. Is there any way to do this WITHOUT change the html? Here's the code:
<ul class="list-inline">
<li>
<a href="http://www.facebook.com/portoseguro" target="_blank">
<span class="gIconSocial fb" style="background: url('https://cliente.portoseguro.com.br/static-files/Institucional/Icones/facebook_off.png') no-repeat !important;">Facebook</span>
</a>
</li>
</ul>
(I can't use javascript too, only css)
