grid with 2 columns

it is possible GRID with two columns, where first image are bigger, and second image are 50% smaller, both in the same row, but smaller image must be align to the center of the bigger in Modula gallery? (client’s fantasy).

I got this code from AI:
but of course .classes{} in Modula are quite different:

[css:]
.gallery {
display: grid;
grid-template-columns: 2fr 1fr; /* First column is twice as wide as the second column / gap: 10px; / Gap between grid items */
}

    .gallery img {
        width: 100%;
        height: auto;
        display: block;
    }

    .smaller {
        align-self: center; /* Align the smaller image to the center vertically within its grid cell */
    }
