Changing Title Color on a Specific Widget

Hi,

I’m having trouble changing the color of a title in WordPress’ own text widget within a pagebuilder row.

I’ve tried giving the widget the ID: #senesteArbejde (I’ve done this under wp admin -> edit page -> selecting the wp text widget -> adding the ID in the ‘Widget ID’ field under attributes), and I then added the following code with the custom CSS widget (under wp admin -> appearances):

#senesteArbejde. h3 {
	color: rgb(00, 00, 00);
}

without any luck.

By the way, when I inspect the title when the site is up, I get this html/css:

<h3 class="widget-title" style="color: rgb(68, 63, 63);">Seneste arbejde</h3>

I also don’t want to change the properties of the widget-title, but only this one specific title, so I can’t use the class name to change anything?

I’m developing locally, so I am sorry that I can’t link the site at the moment.
