how can i upsize the size of a button inside a fullscreen video slide?

Hi,

Please try adding this code to the Quick CSS section under Enfold > General Styling or to your child themes style.css file:

#top .avia-slideshow-button {
    font-size: 16px; 
    padding: 20px 20px;
}
.home #fullscreen_slider_0 .slideshow_align_caption {
    vertical-align: top;
}
.home #fullscreen_slider_0 .avia-slideshow-button {
    display: block;
    max-width: 350px;
    margin: auto;
    margin-top: 10px;
}
.home #fullscreen_slider_0 a.avia-slideshow-button:nth-child(3) {
    color: transparent!important;
    border: none!important;
    background-image: url(https://www.eltern-kongress.com/wp-content/uploads/logo-eltern-kongresss.png)!important;
    background-size: contain!important;
    background-repeat: no-repeat!important;
    background-position: 50% 50%!important;
    background-color: transparent;
}

Hey!

It does look fine on my end. You can add text shadow to your text using following code

.home #fullscreen_slider_0 h2.avia-caption-title {
    text-shadow: 1px 1px #000000;
}

Hey!

Please change following code

#top .avia-fullscreen-slider h2 {
    text-shadow: 1px 1px 7px #000 !important;
}

to following one

#top .avia-fullscreen-slider h2 {
    text-shadow: 1px 1px 7px #fff !important;
    color: black;
    text-align: left;
}
