I have some text on top of an image in a div container that serves as a link.

<a href="https://link.com" style="color:white">
    <div class="thumbnail">
        <img src="image.jpg" class="rnd" alt="image" style="width:100%;">
        <div class="textinimage">some long text</div>
    </div>
</a>

class "rnd" only rounds off the edges of the image

Text is supposed to be centered and cut off if it’s too long for the container

.textinimage {
    font-size:1.1vw;
    width: 90%;
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

class "thumbnail" does the hovering stuff (as well as some opacity), although I am going to be honest, I don’t really know what half of this does as I just copied it from an older project + I’m not very good with CSS

.thumbnail { 
    top:-50px; 
    left:-35px; 
    display:inline-block; 
    z-index:999; 
    cursor: pointer; 
    opacity: 0.5;
    -webkit-transition: all 0.4s ease-in-out;
} 
.thumbnail:hover { 
    transform: scale(1.05);
    opacity: 1;
}

Current issue is that the cutoff seems to only work once I hover over the image/text.
Any idea as to how I can fix this? Feel free to roast and change my CSS btw.

The main issue is that position: relative was missing on .thumbnail. This should work:

.thumbnail {
    position: relative;
    display: inline-flex;
    opacity: 0.5;
    transition: all 0.4s ease-in-out;
}

.thumbnail:hover { 
    transform: scale(1.05);
    opacity: 1;
}

.textinimage {
    position: absolute;
    display: flex;
    top: 0;
    left: 5%;
    right: 5%;
    bottom: 0;
    align-items: center;
}

.textinimage-inner {
    white-space: nowrap;
    text-overflow: ellipsis;
    overflow: hidden;
}

<a href="https://link.com" style="color:white">
    <div class="thumbnail">
        <img src="https://dummyimage.com/300x150/669bc9/fff.png&text=+" class="rnd" alt="image" style="width:100%;">
        <div class="textinimage">
          <div class="textinimage-inner">
            some long text some long text some long text some
          </div>  
        </div>
    </div>
</a>

You have a single issue in your code:

As the image is positioned absolute inside parent .thumbnail (…relative to .thumbnail…), you need to define .thumbnail as a new stacking context to position the image in with .thumbnail { position: relative }

In the snippet I created two custom attributes you can mess with:

[ellipsis] for single line long text ending with ‘…’, the ellipsis
[line-clamp] to limit the number of lines vertically ending with ‘…’, the line-clamp ellipsis.

You cannot use both on a single element, use either/or:

<div class="textinimage" ellipsis>
<div class="textinimage" line-clamp>

I used line-clamp and a lot of textual jibberish…

snippet

[ellipsis], [line-clamp] {
  /* all [MANDATORY] for horizontal ellipsis/vertical line clamp */
    width   : 90%; /* As per original code by OP */
    overflow: hidden;
}
[ellipsis] {
  /* all [MANDATORY] for horizontal text ellipsis */
    white-space: nowrap;
    text-overflow: ellipsis;
}
[line-clamp] {
    /* all [MANDATORY] for vertical line clamp */
    display: -webkit-box;
    -webkit-box-orient: vertical; 
    -webkit-line-clamp: 3;
}

.textinimage {
    font-size: 1.1vw;

    position: absolute; 

    top: 50%; left: 50%;
    transform: translate(-50%, -50%);
}

.thumbnail {
    /* position child elements relative to this */
    position: relative;

    /* Not sure what these are for... disabled them */
    /*top:-50px; 
    left:-35px;*/

    display:inline-block; 
    z-index:999; 
    cursor: pointer; 
    opacity: 0.5;
    -webkit-transition: all 0.4s ease-in-out;
} 
.thumbnail:hover { 
    transform: scale(1.05);
    opacity: 1;
}
.rnd { border-radius: 28px }
