I'm trying to change color of an image via CSS. The image is an element of my website's layout. Here's screenshot showing the element: https://screenshots.firefox.com/xLCsVyZtSKLxFi9F/gameshunt.pl and here is an example post with the table - https://gameshunt.pl/promocje-na-gogu-2-05/
Its code looks like that:
table.tablesorter thead tr th {
background-image: url(/wp-content/plugins/table-sorter/images/bg.gif);
cursor: pointer;
background-repeat: no-repeat;
background-position: right center;
}
I tried background-image: #fff, background image: #fff, url (wp-content/etc)
but nothing works. Does anyone have an idea how to change the color of this element? I can't just upload a different file because the color needs to be different only in dark mode.
