Unable to decrease the width on using mediaqueries to contact form - html

Question

Created a contact form. For making it responsive, i have added a mediquery at 768px to decrease the width of the input field. But it ain't changing.
I will attach the code below for your reference
<div class="form-container">
<h1>send us a message</h1>
<form class="form">
<input id="name" type="text" placeholder="Full Name">
<input id="email" type="text" placeholder="E-Mail">
<textarea id="message" cols="30" rows="10" placeholder="Message"></textarea>
<button type="submit"><i class="fa fa-paper-plane" aria-hidden="true"></i>SEND</button>
</form>
</div>
I used SCSS to style my contact form...
.form-container {
margin: 6rem 0;
height: auto;
h1 {
color: $header-main;
text-align: center;
font-family: $primary-font;
text-transform: capitalize;
font-size: 2.3rem;
letter-spacing: 1px;
&:after {
#include shortBorder(10rem, 1rem, 3px, #111);
margin-bottom: 5rem;
}
}
.form {
input[type="text"],
textarea,button {
display: block;
margin: 2rem auto;
width: 600px;
padding: 1rem;
border-radius: 1rem;
border: 1px solid $plane-white;
box-shadow: 2px 3px 3px 3px #ccc;
outline: none;
transition: width 0.2s ease-in-out;
}
input:hover,
textarea:hover {
width: 620px;
}
::placeholder {
color: rgb(155, 148, 146);
font-weight: 900;
font-family: 'Roboto';
}
button {
background-color: $header-main;
color: $plane-white;
width: 140px;
box-shadow: none;
i {
margin-right: 0.5rem;
}
}
}
button:hover {
cursor: pointer;
width: 160px;
}
}
Media query on contact form.. should decrease to 500px from 600px.
#mediaqueries screen and (max-width:768px) {
.form {
width: 500px;
}
}

Answer 1

There are a bunch of things stopping inputs from shrinking.
You have set rows & columns as size parameters on your text area.
<textarea id="message" cols="30" rows="10" placeholder="Message"></textarea>
This acts as width & height in the HTML. You should remove this and set it with CSS.
Depending on the box-model you're using, margin & padding may be ADDING to the overall width of your elements.
Your media queries aren't targeting the correct elements so it's not being applied as you expect.
Base CSS: (you're changing the width of inputs INSIDE a .form)
.form input[type="text"],
.form textarea,
.form button {
width: 600px;
}
media query (you're changing the form, not the inputs)
.form {
width: 500px;
}
