HTML - CSS

Hello there👋! Congratulations on completing this challenge!

There are no major issues with the code. However, there are a few minor improvements that can be made:

1.The font property should be specified with a unit, e.g. font-weight: 900; should be font-weight: 900; font-size: 15px;.

2.The font property should be spelled out, e.g. font: 900; should be font-weight: 900;.

3.The background-size property should be set to cover instead of contain to ensure that the background image covers the entire background.

Here is the corrected code:

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

body{
    font-family: 'Red Hat Display', sans-serif;
    min-height: 100vh;
    background: url(images/pattern-background-desktop.svg);
    background-repeat: no-repeat;
    background-size: cover;
    background-color: hsl(225, 100%, 94%);   
    position: relative;
    font-size: 16px;
}

.container{
    position: absolute;
    left: 50%;
    top: 50%;
    transform: translate(-50%, -50%);
    max-width: 450px;
    background-color: white;
    border-radius: 20px;
    overflow: hidden;   
}

.text-content{
    padding: 7%;
    text-align: center;
}

.title{
    color: hsl(223, 47%, 23%);
    font-weight: 900;
    font-size: 32px;
    margin-bottom: 20px;
}

.text-content p.subtitle{
    color: #8a8a8a;
    margin-bottom: 25px;
}

.plan-box{
    background-color: hsl(225, 100%, 98%);
    border-radius: 12px;
    display: flex;
    padding: 25px;
    align-items: center;
    justify-content: space-between;
}

.plan-box-left{
    display: flex;
    align-items: center;
    text-align: left;   
}

.plan-box-left div{
    margin-left: 20px;
}

.plan-box-left div h5{
    font-weight: 900;
    font-size: 15px;
    color: hsl(223, 47%, 23%);
}

.plan-box-left div p{
    font-size: 14px;\n    color: #8a8a8a;
}

.plan-box a{

    transition: color cubic-bezier(0.39, 0.575, 0.565, 3) ease;\n}\n\na.proceed-btn{\n    display: block;
    text-decoration: none;
    color: white;
    background-color: hsl(245, 75%, 52%);
    padding: 20px 0;
    border-radius: 12px;
    margin: 30px 0;
}

a.cancel-btn{
    color: hsl(224, 23%, 55%);
    text-decoration: none;
    font-weight: 900;
}

a.proceed-btn:hover{
    background-color: hsl(224, 23%, 55%);
}

.plan-box a:hover{
    text-decoration: none;
    color: hsl(224, 23%, 55%);
}

a.cancel-btn:hover{
    color: hsl(223, 47%, 23%);
}

@media only screen and (max-width: 425px){
    body{
        background-image: url(images/pattern-background-mobile.svg);
        font-size: 14px;
    }
    .container{
        max-width: 87%;
    } 
    
    .title{
        font-size: 23px;
    }
    div.plan-box{
        padding: 12px;
    }

    .plan-box-left div{
        margin-left: 10px;
    }

    a.proceed-btn,
    a.cancel-btn,
    .plan-box{
        font-size: 13px;
    }

    .text-content{
        padding: 9% 7%;
