If someone want to place a welcome text over the slider, you can use this CSS code.
.MagicSlider:before {
content:"Willkommen in der Smart Button Community \A Alles über das Flic Smart Home";
white-space: pre-wrap;
color:#fff;
font-size: 18px;
position:absolute;
margin-top: 50px;
display: flex;
z-index: 4;
justify-content: center;
align-items: center;
width: 100%;
padding:10px 0;
background: rgba(0,0,0,0.3);
text-align: center
}
The "\A" in the content creates a line break if you want it to.
This part of the code is only necessary for the line break
white-space: pre-wrap;
