why is my focus pseudo class not working?-CodePudding

I am making a search bar in my page header using a form element container with input and a button inside it. I am making the form changes color when hover over it and when you click it.

somehow the focus pseudo-class isn't working even though I put :active pseudo-class within the same selector block.

snippets:

/* general css */

* {
    box-sizing: border-box;
}

html, body {
    margin: 0;
    padding: 0;
    font-family: "calibri";
}

.header h2 {
    margin: 15px;
    padding: 10px;
    color: azure;
    
}

.header h2 a {
    color: azure;
    text-decoration: none;
}

.header h2 a:hover {
    color: rgb(255, 24, 81);
}

.sponsers img, .social-media img {
    width: 40px;
}

.sponsers img {
    filter: grayscale(100%);
    -webkit-filter: grayscale(100%);
}

.nav-menu ul{
    margin: 10px;
}

CodePudding user response：

You have to select the input inside the form after that you will get your expected result. Here is the solution

.search-bar input:hover::placeholder {
     color: rgba(236, 220, 220, 0.817);
}

.search-bar input:focus::placeholder {
     color: rgba(67, 60, 60, 0.6);
}
