how can I make that the text camera is in the same length as the other camera text [duplicate]

This is not possible at present (2019/06)* with any CSS layout method.

display:subgrid solves the issue but it has limited non-experimental adoption by browsers as yet.*

*[2019/12 Update] - Subgrid is now shipped in Firefox 71

Support @ CanIuse.com

--

It is enabled, by default, in Firefox 71+ so it is possible to test. Until this is fully adopted Javacript is needed to equalise element heights.

Arguably, you could achieve the same thing without subgrid though it's a bit more of a pain.

In my example, I didn't change the HTML so I use display: contents to sort of bring the children up one level of the DOM tree. But if you can change your markup and don't mind the resulting mess, you could also achieve this without display: contents.

.Grid {
    display: grid;
    grid-gap: 10px;
}
.loon-card {
    display: contents;
}
img {
    width: 100%;
    grid-row-start: 1;
}
.short-description {
    grid-row-start: 2;
}
.long-description {
    grid-row-start: 3;
}
.price {
    grid-row-start: 4;
}
button {
    grid-row-start: 5;
}
