Css border types solid

border

The border shorthand CSS property sets an element’s border. It sets the values of border-width , border-style , and border-color .

Try it

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

/* style */ border: solid; /* width | style */ border: 2px dotted; /* style | color */ border: outset #f33; /* width | style | color */ border: medium dashed green; /* Global values */ border: inherit; border: initial; border: revert; border: revert-layer; border: unset; 

The border property may be specified using one, two, or three of the values listed below. The order of the values does not matter.

Note: The border will be invisible if its style is not defined. This is because the style defaults to none .

Values

Sets the thickness of the border. Defaults to medium if absent. See border-width .

Sets the style of the border. Defaults to none if absent. See border-style .

Sets the color of the border. Defaults to currentcolor if absent. See border-color .

Description

As with all shorthand properties, any omitted sub-values will be set to their initial value. Importantly, border cannot be used to specify a custom value for border-image , but instead sets it to its initial value, i.e., none .

The border shorthand is especially useful when you want all four borders to be the same. To make them different from each other, however, you can use the longhand border-width , border-style , and border-color properties, which accept different values for each side. Alternatively, you can target one border at a time with the physical (e.g., border-top ) and logical (e.g., border-block-start ) border properties.

Borders vs. outlines

Borders and outlines are very similar. However, outlines differ from borders in the following ways:

• Outlines never take up space, as they are drawn outside of an element’s content.
• According to the spec, outlines don’t have to be rectangular, although they usually are.

Formal definition

• border-width : as each of the properties of the shorthand:
  • border-top-width : medium
  • border-right-width : medium
  • border-bottom-width : medium
  • border-left-width : medium
  • border-top-style : none
  • border-right-style : none
  • border-bottom-style : none
  • border-left-style : none
  • border-top-color : currentcolor
  • border-right-color : currentcolor
  • border-bottom-color : currentcolor
  • border-left-color : currentcolor
  • border-width : as each of the properties of the shorthand:
    • border-bottom-width : the absolute length or 0 if border-bottom-style is none or hidden
    • border-left-width : the absolute length or 0 if border-left-style is none or hidden
    • border-right-width : the absolute length or 0 if border-right-style is none or hidden
    • border-top-width : the absolute length or 0 if border-top-style is none or hidden
    • border-bottom-style : as specified
    • border-left-style : as specified
    • border-right-style : as specified
    • border-top-style : as specified
    • border-bottom-color : computed color
    • border-left-color : computed color
    • border-right-color : computed color
    • border-top-color : computed color
    • border-color : as each of the properties of the shorthand:
      • border-bottom-color : a color
      • border-left-color : a color
      • border-right-color : a color
      • border-top-color : a color
      • border-bottom-width : a length
      • border-left-width : a length
      • border-right-width : a length
      • border-top-width : a length

      CSS Borders

      The CSS border properties allow you to specify the style, width, and color of an element’s border.

      I have borders on all sides.

      I have a red bottom border.

      I have a blue left border.

      CSS Border Style

      The border-style property specifies what kind of border to display.

      The following values are allowed:

      • dotted — Defines a dotted border
      • dashed — Defines a dashed border
      • solid — Defines a solid border
      • double — Defines a double border
      • groove — Defines a 3D grooved border. The effect depends on the border-color value
      • ridge — Defines a 3D ridged border. The effect depends on the border-color value
      • inset — Defines a 3D inset border. The effect depends on the border-color value
      • outset — Defines a 3D outset border. The effect depends on the border-color value
      • none — Defines no border
      • hidden — Defines a hidden border

      The border-style property can have from one to four values (for the top border, right border, bottom border, and the left border).

      Example

      Demonstration of the different border styles:

      A groove border. The effect depends on the border-color value.

      A ridge border. The effect depends on the border-color value.

      An inset border. The effect depends on the border-color value.

      An outset border. The effect depends on the border-color value.

      Note: None of the OTHER CSS border properties (which you will learn more about in the next chapters) will have ANY effect unless the border-style property is set!

      border-style

      The border-style shorthand CSS property sets the line style for all four sides of an element’s border.

      Try it

      Constituent properties

      This property is a shorthand for the following CSS properties:

      Syntax

      /* Keyword values */ border-style: none; border-style: hidden; border-style: dotted; border-style: dashed; border-style: solid; border-style: double; border-style: groove; border-style: ridge; border-style: inset; border-style: outset; /* top and bottom | left and right */ border-style: dotted solid; /* top | left and right | bottom */ border-style: hidden double dashed; /* top | right | bottom | left */ border-style: none solid dotted dashed; /* Global values */ border-style: inherit; border-style: initial; border-style: revert; border-style: revert-layer; border-style: unset; 

      The border-style property may be specified using one, two, three, or four values.

      • When one value is specified, it applies the same style to all four sides.
      • When two values are specified, the first style applies to the top and bottom, the second to the left and right.
      • When three values are specified, the first style applies to the top, the second to the left and right, the third to the bottom.
      • When four values are specified, the styles apply to the top, right, bottom, and left in that order (clockwise).

      Each value is a keyword chosen from the list below.

      Values

      Describes the style of the border. It can have the following values:

      Like the hidden keyword, displays no border. Unless a background-image is set, the computed value of the same side’s border-width will be 0 , even if the specified value is something else. In the case of table cell and border collapsing, the none value has the lowest priority: if any other conflicting border is set, it will be displayed.

      Like the none keyword, displays no border. Unless a background-image is set, the computed value of the same side’s border-width will be 0 , even if the specified value is something else. In the case of table cell and border collapsing, the hidden value has the highest priority: if any other conflicting border is set, it won’t be displayed.

      Displays a series of rounded dots. The spacing of the dots is not defined by the specification and is implementation-specific. The radius of the dots is half the computed value of the same side’s border-width .

      Displays a series of short square-ended dashes or line segments. The exact size and length of the segments are not defined by the specification and are implementation-specific.

      Displays a single, straight, solid line.

      Displays two straight lines that add up to the pixel size defined by border-width .

      Displays a border with a carved appearance. It is the opposite of ridge .

      Displays a border with an extruded appearance. It is the opposite of groove .

      Displays a border that makes the element appear embedded. It is the opposite of outset . When applied to a table cell with border-collapse set to collapsed , this value behaves like ridge .

      Displays a border that makes the element appear embossed. It is the opposite of inset . When applied to a table cell with border-collapse set to collapsed , this value behaves like groove .

      Formal definition

      • border-top-style : none
      • border-right-style : none
      • border-bottom-style : none
      • border-left-style : none
      • border-bottom-style : as specified
      • border-left-style : as specified
      • border-right-style : as specified
      • border-top-style : as specified

      Formal syntax

      border-style =
      

      =
      none |
      hidden |
      dotted |
      dashed |

      border

      Универсальное свойство border позволяет одновременно установить толщину, стиль и цвет границы вокруг элемента. Значения могут идти в любом порядке, разделяясь пробелом, браузер сам определит, какое из них соответствует нужному свойству. Для установки границы только на определенных сторонах элемента, воспользуйтесь свойствами border-top , border-bottom , border-left , border-right .

      Синтаксис

      Значения

      Значение border-width определяет толщину границы. Для управления ее видом предоставляется несколько значений border-style . Их названия и результат действия представлен на рис. 1.

      

      border-color устанавливает цвет границы, значение может быть в любом допустимом для CSS формате.

      inherit наследует значение родителя.

      HTML5 CSS2.1 IE Cr Op Sa Fx

      В данном примере вокруг слоя добавляется двойная граница. Результат показан на рис. 2.

      

      Рис. 2. Применение свойства border

      Объектная модель

      [window.]document.getElementById(» elementID «).style.border

      Браузеры

      Браузер Internet Explorer до шестой версии включительно при толщине границы 1px отображает dotted как dashed . При толщине 2px и выше значение dotted работает корректно. Эта ошибка исправлена в IE7, но только для всех границ толщиной 1px. Если одна из границ блока имеет толщину 2px и выше, то в IE7 значение dotted превращается в dashed .

      Internet Explorer до версии 7.0 включительно не поддерживает значение inherit .

      Стиль границы в разных браузерах может несколько различаться при использовании значений groove , ridge , inset или outset .
