Solution 1 :

Edits needed to fix the problem:
Line 55, Css code.

@media (max-width:410px){
    .daughter img{
        padding:10%;
        box-sizing: border-box;
    }
    .son{
        border:1px solid red;
        height: 85vh;
        width: 100%;
    }
    .son p{
        height: 95%;
        text-align: center;
    }
}

Solution 2 :

Apply meta tag in your head section

<meta content="width=device-width, initial-scale=1" name="viewport" />

Replace Style

*{
    margin:0; padding:0; box-sizing: border-box;
   
}

h1{
    text-transform: uppercase;
    margin:50px 0;
    text-align: center;
}
.parent{
    width:100%;
    height:50vh;
    display: flex;
    justify-content: space-around;
    align-self: center;
}
.daughter{
    width:50%;
    text-align: center;
    padding:0;
}
.daughter img{
    width:450px;
}
.son{
    width:50%;
    padding:0 5%;
    box-sizing: border-box;
    line-height: 1.7;
    text-align: justify;
}

@media screen and (max-width: 768px) {
    h1{
        color:red;
    }
    .parent{
        display: block;
    }
    .daughter{
        width:100% !important;
    }
    .son{
        width:100%;
    }
    .parent{display: inline;}
}
@media (max-width:468px){
    .daughter img{
        padding:10%;
        box-sizing: border-box;
    }
    
}
@media (max-width:410px){
    .daughter img{
        padding:10%;
        box-sizing: border-box;
    }
    .son{
        border:1px solid red;
    }
    
}

<h1>My WEBSITE</h1>
