Види розміщення

Розміщеним елементом називають елемент, чиє {{cssxref("computed_value", "обчислене значення")}} властивості position — relative, absolute, fixed, або sticky. Інакше кажучи, все окрім static.
Елементом з відносним розміщенням називають елемент, чиє {{cssxref("computed_value", "обчислене значення")}} властивості position — relative. Властивості {{Cssxref("top")}} і {{Cssxref("bottom")}} вказують доземний (вертикальний) зсув від початкового положення; натомість властивості {{Cssxref("left")}} і {{Cssxref("right")}} визначають поземний (горизонтальний) зсув.
Елементом з абсолютним розміщенням називають елемент, чиє {{cssxref("computed_value", "обчислене значення")}} властивості position — absolute або fixed. Властивості {{Cssxref("top")}}, {{Cssxref("right")}}, {{Cssxref("bottom")}} та {{Cssxref("left")}} вказують зсуви від країв блока, що містить елемент (себто той блок є батьківським і відносно нього здійснюється розміщення елемента). Якщо елемент має {{cssxref("margin", "відступи")}}, то вони додаються до зсувів.
Елементом з «липким» розміщенням називають елемент, чиє {{cssxref("computed_value", "обчислене значення")}} властивості position — sticky. До певної межі (поки блок, всередині якого той елемент розташовано, не перетинає зазначеного порогового значення) це працює так само, як відносне розміщення, а тоді — як нерухоме (fixed).

Most of the time, absolutely positioned elements that have {{Cssxref("height")}} and {{Cssxref("width")}} set to auto are sized so as to fit their contents. However, non-replaced absolutely positioned elements can be made to fill the available vertical space by specifying both {{Cssxref("top")}} and {{Cssxref("bottom")}} and leaving {{Cssxref("height")}} unspecified (that is, auto). They can likewise be made to fill the available horizontal space by specifying both {{Cssxref("left")}} and {{Cssxref("right")}} and leaving {{Cssxref("width")}} as auto.

Except for the case just described of absolutely positioned elements filling the available space:

If both top and bottom are specified (technically, not auto), top wins.
If both left and right are specified, left wins when {{Cssxref("direction")}} is ltr (English, horizontal Japanese, etc.) and right wins when {{Cssxref("direction")}} is rtl (Persian, Arabic, Hebrew, etc.).

Синтаксис

Значення властивості position може бути одним із ключових слів, що їх перелік наведено нижче.

Значення

static: The element is positioned according to the normal flow of the document. The {{cssxref("top")}}, {{cssxref("right")}}, {{cssxref("bottom")}}, {{cssxref("left")}}, and {{cssxref("z-index")}} properties have no effect. This is the default value.
relative: The element is positioned according to the normal flow of the document, and then offset relative to itself based on the values of top, right, bottom, and left. The offset does not affect the position of any other elements; thus, the space given for the element in the page layout is the same as if position were static. This value creates a new stacking context when the value of z-index is not auto. The effect of relative on table-*-group, table-row, table-column, table-cell, and table-caption elements is undefined.
absolute: The element is removed from the normal document flow; no space is created for the element in the page layout. Instead, it is positioned relative to its closest positioned ancestor if any; otherwise, it is placed relative to the initial containing block. Its final position is determined by the values of top, right, bottom, and left. This value creates a new stacking context when the value of z-index is not auto. Absolutely positioned boxes can have margins, and they do not collapse with any other margins.
fixed: The element is removed from the normal document flow; no space is created for the element in the page layout. Instead, it is positioned relative to the screen's viewport and doesn't move when scrolled. Its final position is determined by the values of top, right, bottom, and left. This value always creates a new stacking context. When an ancestor has the transform property set to something other than none, that ancestor is used as the container instead of the viewport (see CSS Transforms Spec). In printed documents, the element is placed in the same position on every page.

sticky {{experimental_inline}}: The element is positioned according to the normal flow of the document, and then offset relative to its flow root and containing block based on the values of top, right, bottom, and left. The offset does not affect the position of any other elements. This value always creates a new stacking context. The effect of sticky on table-related elements is the same as relative. Note that sticky, by specification, will not work inside element with overflow: hidden or auto. (ref: Github issue on W3C CSSWG)

Приклади

Відносне розміщення

Relatively positioned elements are offset a given amount from their normal position within the document, but without the offset affecting other elements. In the example below, note how the other elements are placed as if "Two" were taking up the space of its normal location.

HTML

<div class="box" id="one">One</div>
<div class="box" id="two">Two</div>
<div class="box" id="three">Three</div>
<div class="box" id="four">Four</div>

CSS

.box {
  display: inline-block;
  width: 100px;
  height: 100px;
  background: red;
  color: white;
}

#two {
  position: relative;
  top: 20px;
  left: 20px;
  background: blue;
}

Абсолютне розміщення

Elements that are relatively positioned remain in the normal flow of the document. In contrast, an element that is absolutely positioned is taken out of the flow; thus, other elements are positioned as if it did not exist. The absolutely positioned element is positioned relative to its nearest positioned ancestor (i.e., the nearest ancestor that is not static). If a positioned ancestor doesn't exist, the initial container is used. In the example below, box "Two" has no positioned ancestor, so it is positioned relative to the the <body> of the document.

HTML

<div class="box" id="one">One</div>
<div class="box" id="two">Two</div>
<div class="box" id="three">Three</div>
<div class="box" id="four">Four</div>

CSS

.box {
  display: inline-block;
  width: 100px;
  height: 100px;
  background: red;
  color: white;
}

#two {
  position: absolute;
  top: 20px;
  left: 20px;
  background: blue;
}

Нерухоме розміщення

Fixed positioning is similar to absolute positioning, with the exception that the element's containing block is the viewport. This can be used to create a floating element that stays in the same position regardless of scrolling. In the example below, box "One" is fixed at 80 pixels from the top of the page and 10 pixels from the left. Even after scrolling, it remains in the same place relative to the viewport.

«Липке» розміщення

Sticky positioning can be thought of as a hybrid of relative and fixed positioning. A stickily positioned element is treated as relatively positioned until it crosses a specified threshold, at which point it is treated as fixed. For instance...

#one { position: sticky; top: 10px; }

...would position the element with id one relatively until the viewport were scrolled such that the element would be less than 10 pixels from the top. Beyond that threshold, the element would be fixed to 10 pixels from the top.

A common use for sticky positioning is for the headings in an alphabetized list. The "B" heading will appear just below the items that begin with "A" until they are scrolled offscreen. Rather than sliding offscreen with the rest of the content, the "B" heading will then remain fixed to the top of the viewport until all the "B" items have scrolled offscreen, at which point it will be covered up by the "C" heading, and so on.

You must specify a threshold with at least one of top, right, bottom, or left for sticky positioning to behave as expected. Otherwise, it will be indistinguishable from relative positioning.

[1] Since Firefox 30, Gecko allows {{HTMLElement("tr")}}, {{HTMLElement("thead")}}, and {{HTMLElement("tfoot")}} elements with a position: relative; style to act as absolute positioning containers. This means that a position: absolute; styled element inside the table can be positioned relative to these elements. In other browsers and in older versions of Firefox, setting position: relative; on a table row or row group has no effect. Firefox helps developers transition to the new behavior and detect any rendering issues it may cause on their sites by printing a warning to the JavaScript console if you use this feature: Relative positioning of table rows and row groups is now supported. This site may need to be updated because it may depend on this feature having no effect.

[2] In Firefox 26 to Firefox 31 (inclusive), sticky positioning only works when the about:config preference layout.css.sticky.enabled is set to true. From Firefox 27 to 31, true is the default value for Nightly and Aurora versions of the browser. The preference has been removed in Firefox 48.

[3] In Internet Explorer, fixed positioning doesn't work if the document is in quirks mode.

[4] Prior to Firefox 44, position: fixed didn't create a stacking context in most cases. The specification, and Gecko implementation, have been modified to mimic Chrome and Safari's long-time behavior.

[5] Sticky positioning is in preview for Edge.
