Product description width

TYry this CSS

.woocommerce-tabs .panel {
    margin-left: 0px !important;
}

Thanks

Not working.
I have removed the Tabs with plugin WooCommerce Expand Tabs, but the plugin only hides the Tabs, not removes them, maybe that was the problem, why the Product Description width was not full width, so I have stopped using the plugin, so the Tabs are still there.

I have tried to use this CSS to remove the Product Tabs, but without success :
.woocommerce-tabs .tabs li a { display: none !important; }

I have updated the style.css file and the Custom CSS in Avada – Theme options, nothing helped so far.

OK, now I’m bit lost ??
I have used this to make it all as I want :
.woocommerce-tabs .panel
{ padding: 200px !important; }

.woocommerce-tabs .panel
{ margin-left: 50px !important; }

.woocommerce-tabs .tabs li a
{ display: none !important; }

I typed it into Avada – Theme options – Custom CSS

Nothing happened.
So I went to Appearances – Editor – style.css, but it said, I don’t need to use it like this, I can change the CSS in built-in editor, to see the changes realtime. I used it, and in here, the Product Tabs were gone, everything was as it should be…

So I refreshed my browser, but nothing changed, the Tabs were still there.
So I removed the code from the Avada Custom CSS, went to the built-in editor and the Tabs were there. So clearly, the code works, as it should be, only I can’t see the changes in my browser.
I even used another browser, which I haven’t used and the Tabs are still there, so I’m lost here now. Are the Tabs there or not? ??

I did “empty all chaches” in Worpress, Product Tabs are still showing in my browsers, and NOT showing in buit-in editor in WordPress.

OK, code is definitely working, but only in built-in editor, I will make new topic.
