CSS Forms

The look of an HTML form can be greatly improved with CSS:

Styling Input Fields

Use the width property to determine the width of the input field:

The example above applies to all <input> elements. If you only want to style a specific input type, you can use attribute selectors:

• input[type=text] - will only select text fields
• input[type=password] - will only select password fields
• input[type=number] - will only select number fields
• etc..

Padded Inputs

Use the padding property to add space inside the text field.

Tip: When you have many inputs after each other, you might also want to add some margin, to add more space outside of them:

Note that we have set the box-sizing property toborder-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.

Bordered Inputs

Use the border property to change the border size and color, and use the border-radius property to add rounded corners:

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

Colored Inputs

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

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 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:

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.

Styling Textareas

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

Styling Select Menus

Styling Input Buttons

Responsive Form

Resize the browser window to see the effect. When the screen is less than 600px wide, make the two columns stack on top of each other instead of next to each other.
