CSS code

.main{
    border: 2px solid magenta;
    background-color: #bebdbd;
    position: absolute;
    width: 30vw;

    display:grid;
    flex-direction: column;
}

*{
    margin: 0;
    padding: 0;
}
.box{
    /* border: 2px solid black;  */
    overflow: hidden;
}
.box img{
    width: 200px;
    border-radius: 4px;
}

.main .box:hover .overlay{
    height: 100px;
    /* position: absolute; */
    z-index: 999;
    top: 0.5%;
    transition-delay:0s;
    transition-timing-function: linear;
    transition-duration: 300ms;
}

.overlay{
    position: absolute;
    top: -11%;
    background-color: #ffffff4e;
    width: 190px;
    height: 0px;
    overflow: hidden;
    padding: 5px;
    backdrop-filter: blur(16px);
}

#moviebox{
    position: relative;
    /* border: 2px solid red; */
    height: fit-content;
    width: 100%;
    display: flex;
    gap: 1rem;
    overflow: hidden;
    flex-wrap: wrap;
    padding: 5px;

}

#search{
    border: none;
    margin: 5vh 0vw 5vh 4vw;
    height: 5vh;
    width: 30vw;
    border-radius: 3px;
    padding-left: 2%;
    background-color: #949292;
    color: white;
    outline: none;
    font-size: 23px;
}

I was trying to make the overlay come on the top of each image element on hovering the image element. But when i hover the image elements that are below the top elements then top elements are hover triggered , i was expecting that each element will show overlays on hovering the corresponding box element .

Solution

  • Because you are using absolute positioning, each overlay is being positioned at the very top. What you need to do is add position: relative to the .box rule.

    .main{
    border: 2px solid magenta;
    background-color: #bebdbd;
    position: absolute;
    width: 30vw;

    display:grid;
    flex-direction: column;
}

*{
    margin: 0;
    padding: 0;
}
.box{
    /* border: 2px solid black;  */
    overflow: hidden;
    position: relative; /* <-- */
}
.box img{
    width: 200px;
    border-radius: 4px;
}

.main .box:hover .overlay{
    height: 100px;
    /* position: absolute; */
    z-index: 999;
    top: 0.5%;
    transition-delay:0s;
    transition-timing-function: linear;
    transition-duration: 300ms;
}

.overlay{
    position: absolute;
    top: -11%;
    background-color: #ffffff4e;
    width: 190px;
    height: 0px;
    overflow: hidden;
    padding: 5px;
    backdrop-filter: blur(16px);
}

#moviebox{
    position: relative;
    /* border: 2px solid red; */
    height: fit-content;
    width: 100%;
    display: flex;
    gap: 1rem;
    overflow: hidden;
    flex-wrap: wrap;
    padding: 5px;

}

#search{
    border: none;
    margin: 5vh 0vw 5vh 4vw;
    height: 5vh;
    width: 30vw;
    border-radius: 3px;
    padding-left: 2%;
    background-color: #949292;
    color: white;
    outline: none;
    font-size: 23px;
