CSS Forms

<form action='' method=''>

<input type='text' name='name'/>

<input type='Email' name='Email'/>

<input type='submit' name='submit'/>

</form>

input[type=text] {
    width: 100%;
    padding: 12px 20px;
    margin: 8px 0;
    box-sizing: border-box;}

Note that we have set the box-sizing property to border-box. This makes sure that the padding and eventually borders are included in the total width and height of the elements. 
Read more about the box-sizing property in our CSS Box Sizing chapter.

input[type=text] {
    border: 2px solid red;
    border-radius: 4px;}

If you only want a bottom border, use the border-bottom property:

First Name

input[type=text] {
    border: none;
    border-bottom: 2px solid red;}

Colored Inputs

Use the background-color property to add a background color to the input, and the color property to change the text color:

input[type=text] {
    background-color: #3CBC8D;
    color: white;}

Focused Inputs

By default, some browsers will add a blue outline around the input when it gets focus (clicked on). You can remove this behavior by adding outline: none; to the input.

Use the :focus selector to do something with the input field when it gets focus:

input[type=text]:focus {
    background-color: lightblue;}

input[type=text]:focus {
    border: 3px solid #555;}

Input with icon/image

If you want an icon inside the input, use the background-image property and position it with the background-position property. Also notice that we add a large left padding to reserve the space of the icon:

input[type=text] {
    background-color: white;
    background-image: url('searchicon.png');
    background-position: 10px 10px; 
    background-repeat: no-repeat;
    padding-left: 40px;}

Animated Search Input

In this example we use the CSS transition property to animate the width of the search input when it gets focus. You will learn more about the transition property later, in our CSS Transitions chapter.

input[type=text] {
    -webkit-transition: width 0.4s ease-in-out;
    transition: width 0.4s ease-in-out;}

input[type=text]:focus {
    width: 100%;}

Styling Textareas

Tip: Use the resize property to prevent textareas from being resized (disable the "grabber" in the bottom right corner):

textarea {
    width: 100%;
    height: 150px;
    padding: 12px 20px;
    box-sizing: border-box;
    border: 2px solid #ccc;
    border-radius: 4px;
    background-color: #f8f8f8;
    resize: none;}

Styling Select Menus

select {
    width: 100%;
    padding: 16px 20px;
    border: none;
    border-radius: 4px;
    background-color: #f1f1f1;}

Styling Input Buttons

input[type=button], input[type=submit], input[type=reset] {
    background-color: #4CAF50;
    border: none;
    color: white;
    padding: 16px 32px;
    text-decoration: none;
    margin: 4px 2px;
    cursor: pointer;}
