Remove colour and underline on hyperlinks and replace with a hover over colour, please help!

In the clients section I am trying to remove the colour and underline on hyperlinks and replace with a hover over colour. I have managed to do this however my code is affecting my site title and turning it black, and it should be white. 

The code I am using currently is - 
 

/* link hover color */
a {
  color: inherit !important;
  text-decoration: none !important;
}

a:hover {
  color: #5C63E4 !important;
  text-decoration: none !important;
}

//remove underlines from hyperlinks//

.sqs-block-html a {background-image:none!important}

/* Remove non-background image underline for heading and paragraph links */
h1 a, h2 a, h3 a, h4 a, p a {text-decoration: none!important}

Site password - test

Can you share the website URL?

I can't see anything in your CSS that would turn the website black, but I'd be happy to take a look.

Solved I think with 
 

/* link hover color */
.fe-63cfec583e981e02c537c53e a {
  color: inherit !important;
  text-decoration: none !important;
}

.fe-63cfec583e981e02c537c53e a:hover {
  color: #5C63E4 !important;
  text-decoration: none !important;
}

//remove underlines from hyperlinks//

.sqs-block-html a {background-image:none!important}

/* Remove non-background image underline for heading and paragraph links */
h1 a, h2 a, h3 a, h4 a, p a {text-decoration: none!important}
