How to hide these elements?

Question

Layout

Tried with z-index, overflow:hidden didn't help. Maybe I did not use it correctly, but I tried it in different ways and it did not work. In general, blocks with text should overlap the numbers and the line.

main.css:143 line and everything is implemented like this

.block1__img::before {
    display: block;
    content: "01";
    color: #e8c3c2;
    font-family: Montserrat;
    font-size: 150px;
    font-weight: 700;
    letter-spacing: 11.25px;
    position: relative;
    left: 0%;
    top: 66%;
    transform: translateX(-45%);
    z-index: -100;
}
