    background-color: #8BC34A;

Hope this helps.

Hello @itsme2018,

As for the header menu, the CSS worked when we tested it locally. Since it is not working for you please post your site URL so that we can provide a precise fix on this.

Now to change the color of the sale tag replace the code given below:

.woocommerce ul.products li.product span.onsale {
    display: none;
}

With this code:

.woocommerce ul.products li.product span.onsale {
    background-color: #9db51f;
}

Hope this helps.

Best Regards!!

Hello @itsme2018,

When we inspected your site URL we could not find the top left menu so we are unable to provide any fix.

So please set the top left menu and let us know.

Thank you.

Best Regards!!
