Css padding text box

CSS Padding

Padding is used to create space around an element’s content, inside of any defined borders.

CSS Padding

The CSS padding properties are used to generate space around an element’s content, inside of any defined borders.

With CSS, you have full control over the padding. There are properties for setting the padding for each side of an element (top, right, bottom, and left).

Padding — Individual Sides

CSS has properties for specifying the padding for each side of an element:

All the padding properties can have the following values:

  • length — specifies a padding in px, pt, cm, etc.
  • % — specifies a padding in % of the width of the containing element
  • inherit — specifies that the padding should be inherited from the parent element

Note: Negative values are not allowed.

Example

Set different padding for all four sides of a element:

Padding — Shorthand Property

To shorten the code, it is possible to specify all the padding properties in one property.

The padding property is a shorthand property for the following individual padding properties:

If the padding property has four values:

  • padding: 25px 50px 75px 100px;
    • top padding is 25px
    • right padding is 50px
    • bottom padding is 75px
    • left padding is 100px

    Example

    Use the padding shorthand property with four values:

    If the padding property has three values:

    • padding: 25px 50px 75px;
      • top padding is 25px
      • right and left paddings are 50px
      • bottom padding is 75px

      Example

      Use the padding shorthand property with three values:

      If the padding property has two values:

      • padding: 25px 50px;
        • top and bottom paddings are 25px
        • right and left paddings are 50px

        Example

        Use the padding shorthand property with two values:

        If the padding property has one value:

        Example

        Use the padding shorthand property with one value:

        Padding and Element Width

        The CSS width property specifies the width of the element’s content area. The content area is the portion inside the padding, border, and margin of an element (the box model).

        So, if an element has a specified width, the padding added to that element will be added to the total width of the element. This is often an undesirable result.

        Example

        Here, the element is given a width of 300px. However, the actual width of the element will be 350px (300px + 25px of left padding + 25px of right padding):

        To keep the width at 300px, no matter the amount of padding, you can use the box-sizing property. This causes the element to maintain its actual width; if you increase the padding, the available content space will decrease.

        Example

        Use the box-sizing property to keep the width at 300px, no matter the amount of padding:

        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:

        Example

        The example above applies to all 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:

        Example

        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.

        Bordered Inputs

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

        Example

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

        Example

        Colored Inputs

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

        Example

        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:

        Example

        Example

        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:

        Example

        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.

        Example

        input[type=text] <
        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):

        Example

        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

        Example

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

        Styling Input Buttons

        Example

        input[type=button], input[type=submit], input[type=reset] <
        background-color: #04AA6D;
        border: none;
        color: white;
        padding: 16px 32px;
        text-decoration: none;
        margin: 4px 2px;
        cursor: pointer;
        >

        /* Tip: use width: 100% for full-width 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.

        Advanced: The following example uses media queries to create a responsive form. You will learn more about this in a later chapter.

        padding

        Устанавливает значение полей вокруг содержимого элемента. Полем называется расстояние от внутреннего края рамки элемента до воображаемого прямоугольника, ограничивающего его содержимое (рис. 1).

        Рис. 1. Поле слева от текста

        Рис. 1. Поле слева от текста

        Свойство padding позволяет задать величину поля сразу для всех сторон элемента или определить ее только для указанных сторон.

        Синтаксис

        padding: [значение | проценты] | inherit

        Значения

        Разрешается использовать одно, два, три или четыре значения, разделяя их между собой пробелом. Эффект зависит от количества значений и приведен в табл. 1.

        Табл. 1. Зависимость от числа значений

        Число значений Результат
        1 Поля будут установлены одновременно от каждого края элемента.
        2 Первое значение устанавливает поля от верхнего и нижнего края, второе — от левого и правого.
        3 Первое значение задает поле от верхнего края, второе — одновременно от левого и правого края, а третье — от нижнего края.
        4 Поочередно устанавливается поля от верхнего, правого, нижнего и левого края.

        Величину полей можно указывать в пикселах (px), процентах (%) или других допустимых для CSS единицах. Значение inherit указывает, что оно наследуется у родителя. При указании поля в процентах, значение считается от ширины родителя элемента.
