With CSS, you can style most of the different input types, like text fields, password fields, checkboxes, radio buttons, and file inputs. You can also style input labels and form buttons. Some commonly used CSS properties for styling input fields, are:
Formula
width padding margin border border - radius background - color color font - sizeThe width property is used to set the width of an input field.
The default width of an HTML input text field, is 20 characters. Here we set the width to 100%:
{
width: 100%;
}The example above applies to all <input> elements. If you only want to style a specific input type, you can use attribute selectors
Formula
input[type = text]
- will only select text fields input[type = password]
- will only select password fields input[type = number]The padding property is used to add some space inside the text field.
When you have several input fields after each other, you might also want to add some margin, to add more space around them:
Example input[type=text]
{
width: 100%;
padding: 12px;
margin: 10px 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.
Formula
Read more about the box - sizing property in ourCSS Box Sizing chapter.
The border property is used to change the border size and color, and the border-radius property can be used to add rounded corners:
Example input[type=text]
{
border: 2px solid red;
border-radius: 8px;
}Formula
If you only want a bottom border, use the border - bottom property:Example input[type=text]
{
border: none;
border-bottom: 1px solid red;
}The background-color property is used to add a background color to the input, and the color property is used to change the text color:
Example input[type=text]
{
background-color: #3CBC8D;
color: white;
}
