CSS help

Hi,

I’ve already made modifications myself hiding elements and changing colours.
I am having difficulties with changing default text and colour of some specific elements which I am unable to solve on my own.

The site is in staging environment so cannot post here unfortunately. I’ll try to be as specific as possible without it.

1. I would like to remove the word ‘reservieren’ in

‘<div class>=”tribe-tickets__rsvp-actions-rsvp”>
<span class=”tribe-common-h2 tribe-common-h6–min-medium”>
Hier reservieren </span>’

2. I would like to change the word ‘Reservieren’ to ‘Anmelden’.

‘<div class>=”tribe-tickets__rsvp-actions-rsvp-going”>
<button class=”tribe-common-c-btn tribe-tickets__rsvp-actions-button-going tribe-common-b1 tribe-common-b2–min-medium” type=”submit”>
Reservieren </button>’

3. On an event’s individual page I would like to change the link colour of navigation elements at the bottom left and right of the page. I would like to change the colour of
both states, normal and mouse on. I have already tried adding the statement ‘colour: #fffffff’ and ‘color: white’ to various elements like ‘tribe-events-nav-previous’ and ‘tribe-events-nav-next.`

Thanks for any help you are able to offer other than telling me to buy a license.
Much appreciated.
