How to remove underlines for toolbar?

I have a toolbar under a tab , I want to remove underlines (as seen in red box in image) because I do not want to use us to change some page, instead I use it for actions,"tabActiveVideo")
      .page-content.messages-content.a"activeCall.state === 'RINGING'") {{ $t('CALLING') }} {{activeCall.calleeName}}"getVideoCallOption && !startCall", @click='makeCall(true)')
 Video {{activeCall.calleeName}}


Hello, my solution for this was to override the css. I keep the background color but make the alpha 0 so it’s completely transparent. However, for I would take this code and give it its own class and add it to each of your tabs so it maintains the underline on voice.

.md .tabbar .tab-link-highlight, .md .tabbar-labels .tab-link-highlight {
    position: absolute;
    bottom: 0;
    height: 3px;
    background: rgba(255,255,255,0) !important;
    background-image: initial;
    background-position-x: initial;
    background-position-y: initial;
    background-size: initial;
    background-repeat-x: initial;
    background-repeat-y: initial;
    background-attachment: initial;
    background-origin: initial;
    background-clip: initial;
    background-color: rgba(255, 255, 255, 0) !important;
    -webkit-transition-duration: .3s;
    transition-duration: .3s;
    left: 0;

Add this line to your main file:
<style>.tab-link-highlight {display:none;}</style>


Thank you! You saved me a few hours!
