float

Определяет, по какой стороне будет выравниваться элемент, при этом остальные элементы будут обтекать его с других сторон. Когда значение свойства float равно none , элемент выводится на странице как обычно, при этом допускается, что одна строка обтекающего текста может быть на той же линии, что и сам элемент.

Синтаксис

float: left | right | none | inherit

Значения

left Выравнивает элемент по левому краю, а все остальные элементы, вроде текста, обтекают его по правой стороне. right Выравнивает элемент по правому краю, а все остальные элементы обтекают его по левой стороне. none Обтекание элемента не задается. inherit Наследует значение родителя.

Браузеры

В браузере Internet Explorer 6 наблюдается ошибка с удвоением значения левого или правого отступа для плавающих элементов, вложенных в родительские элементы. Удваивается тот отступ, который прилегает к стороне родителя. Проблема обычно решается добавлением display: inline для плавающего элемента. Также в этом браузере добавляется отступ 3px (так называемый «трехпиксельный баг») в направлении, заданном значением float .

Internet Explorer до версии 7.0 включительно не поддерживает значение inherit .

CSS Layout — float and clear

The CSS float property specifies how an element should float.

The CSS clear property specifies what elements can float beside the cleared element and on which side.

The float Property

The float property is used for positioning and formatting content e.g. let an image float left to the text in a container.

The float property can have one of the following values:

left — The element floats to the left of its container
right — The element floats to the right of its container
none — The element does not float (will be displayed just where it occurs in the text). This is default
inherit — The element inherits the float value of its parent

In its simplest use, the float property can be used to wrap text around images.

Example — float: right;

The following example specifies that an image should float to the right in a text:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus imperdiet, nulla et dictum interdum, nisi lorem egestas odio, vitae scelerisque enim ligula venenatis dolor. Maecenas nisl est, ultrices nec congue eget, auctor vitae massa. Fusce luctus vestibulum augue ut aliquet. Mauris ante ligula, facilisis sed ornare eu, lobortis in odio. Praesent convallis urna a lacus interdum ut hendrerit risus congue. Nunc sagittis dictum nisi, sed ullamcorper ipsum dignissim ac.

Example

Example — float: left;

The following example specifies that an image should float to the left in a text:

Example

Example — No float

In the following example the image will be displayed just where it occurs in the text (float: none;):

Example

Example — Float Next To Each Other

Normally div elements will be displayed on top of each other. However, if we use float: left we can let elements float next to each other:

float

The float CSS property places an element on the left or right side of its container, allowing text and inline elements to wrap around it. The element is removed from the normal flow of the page, though still remaining a part of the flow (in contrast to absolute positioning).

Try it

A floating element is one where the computed value of float is not none .

As float implies the use of the block layout, it modifies the computed value of the display values, in some cases:

Specified value	Computed value
inline	block
inline-block	block
inline-table	table
table-row	block
table-row-group	block
table-column	block
table-column-group	block
table-cell	block
table-caption	block
table-header-group	block
table-footer-group	block
inline-flex	flex
inline-grid	grid
other	unchanged

Note: If you’re referring to this property from JavaScript as a member of the HTMLElement.style object, modern browsers support float , but in older browsers you have to spell it as cssFloat . This was an exception to the rule, that the name of the DOM member is the camel-case name of the dash-separated CSS name (because «float» is a reserved word in JavaScript, as seen in the need to escape «class» as «className» and escape ‘s «for» as «htmlFor»).

Syntax

/* Keyword values */ float: left; float: right; float: none; float: inline-start; float: inline-end; /* Global values */ float: inherit; float: initial; float: revert; float: revert-layer; float: unset;

The float property is specified as a single keyword, chosen from the list of values below.

Values

The element must float on the left side of its containing block.

The element must float on the right side of its containing block.

The element must not float.

The element must float on the start side of its containing block. That is the left side with ltr scripts, and the right side with rtl scripts.

The element must float on the end side of its containing block. That is the right side with ltr scripts, and the left side with rtl scripts.

Formal definition

Initial value	none
Applies to	all elements, but has no effect if the value of display is none .
Inherited	no
Computed value	as specified
Animation type	discrete

Formal syntax

=
snap-block( , [ start | end | near ]? )

=
snap-inline( , [ left | right | near ]? )

Examples

How floated elements are positioned

As mentioned above, when an element is floated, it is taken out of the normal flow of the document (though still remaining part of it). It is shifted to the left, or right, until it touches the edge of its containing box, or another floated element.

In this example, there are three colored squares. Two are floated left, and one is floated right. Note that the second «left» square is placed to the right of the first. Additional squares would continue to stack to the right, until they filled the containing box, after which they would wrap to the next line.

A floated element is at least as tall as its tallest nested floated children. We gave the parent width: 100% and floated it to ensure it is tall enough to encompass its floated children, and to make sure it takes up the width of the parent so we don’t have to clear its adjacent sibling.

HTML

section> div class="left">1div> div class="left">2div> div class="right">3div> p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Morbi tristique sapien ac erat tincidunt, sit amet dignissim lectus vulputate. Donec id iaculis velit. Aliquam vel malesuada erat. Praesent non magna ac massa aliquet tincidunt vel in massa. Phasellus feugiat est vel leo finibus congue. p> section>

CSS

section  box-sizing: border-box; border: 1px solid blue; width: 100%; float: left; > div  margin: 5px; width: 50px; height: 150px; > .left  float: left; background: pink; > .right  float: right; background: cyan; >

Result

Clearing floats

Sometimes you may want to force an item to move below any floated elements. For instance, you may want paragraphs to remain adjacent to floats, but force headings to be on their own line. See clear for examples.
