Css overflow not wrapping

overflow

The overflow CSS shorthand property sets the desired behavior when content does not fit in the parent element box (overflows) in the horizontal and/or vertical direction.

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

/* Keyword values */ overflow: visible; overflow: hidden; overflow: clip; overflow: scroll; overflow: auto; overflow: hidden visible; /* Global values */ overflow: inherit; overflow: initial; overflow: revert; overflow: revert-layer; overflow: unset; 

Values

Overflow content is not clipped and may be visible outside the element’s padding box. The element box is not a scroll container. This is the default value of the overflow property.

Overflow content is clipped at the element’s padding box. There are no scroll bars, and the clipped content is not visible (i.e., clipped content is hidden), but the content still exists. User agents do not add scroll bars and also do not allow users to view the content outside the clipped region by actions such as dragging on a touch screen or using the scroll wheel on a mouse. The content can be scrolled programmatically (for example, by setting the value of the scrollLeft property or the scrollTo() method), in which case. The element box is a scroll container.

Overflow content is clipped at the element’s overflow clip edge that is defined using the overflow-clip-margin property. As a result, content overflows the element’s padding box by the value of overflow-clip-margin or by 0px if not set. Overflow content outside the clipped region is not visible, user agents do not add a scroll bar, and programmatic scrolling is also not supported. No new formatting context is created. To establish a formatting context, use overflow: clip along with display: flow-root . The element box is not a scroll container.

Overflow content is clipped at the element’s padding box, and overflow content can be scrolled into view using scroll bars. User agents display scroll bars in both horizontal and vertical directions if only one value is set, whether or not any content is overflowing or clipped. The use of this keyword, therefore, can prevent scroll bars from appearing and disappearing as content changes. Printers may still print overflowing content. The element box is a scroll container.

Overflow content is clipped at the element’s padding box, and overflow content can be scrolled into view. Unlike scroll , user agents display scroll bars only if the content is overflowing and hide scroll bars by default. If content fits inside the element’s padding box, it looks the same as with visible but still establishes a new formatting context. The element box is a scroll container.

Note: The keyword value overlay is a legacy value alias for auto . With overlay , the scroll bars are drawn on top of the content instead of taking up space.

Description

Overflow options include hiding overflowing content, enabling scroll bars to view overflow content or displaying the content flowing out of an element box into the surrounding area, and combinations there of.

The following nuances should be kept in mind while using the various keywords for overflow :

• Specifying a value other than visible (the default) or clip for overflow creates a new block formatting context. This is necessary for technical reasons; if a float intersects with a scrolling element, it would forcibly rewrap the content after each scroll step, leading to a slow scrolling experience.
• For an overflow setting to create the desired effect, the block-level element must have either a set height ( height or max-height ) or white-space set to nowrap .
• Setting one axis to visible (the default) while setting the other to a different value results in visible behaving as auto .
• The JavaScript Element.scrollTop property may be used to scroll through content in a scroll container, including when overflow is set to hidden .

Formal definition

• overflow-x : as specified, except with visible / clip computing to auto / hidden respectively if one of overflow-x or overflow-y is neither visible nor clip
• overflow-y : as specified, except with visible / clip computing to auto / hidden respectively if one of overflow-x or overflow-y is neither visible nor clip

Formal syntax

overflow =
[ visible | hidden | clip | scroll | auto ]

Accessibility concerns

A scrolling content area cannot be scrolled by a keyboard-only user, with the exception of users on Firefox (which makes the container keyboard focusable by default).

As a developer, to allow non-Firefox keyboard-only users to scroll the container, you will need to give it a tabindex using tabindex=»0″ . Unfortunately, when a screen reader encounters this tab-stop, they will have no context for what it is and their screen reader will likely announce the entirety of its contents. Giving it an appropriate WAI-ARIA role ( role=»region» , for example) and an accessible name (via aria-label or aria-labelledby ) can mitigate this.

overflow-wrap

The overflow-wrap CSS property applies to inline elements, setting whether the browser should insert line breaks within an otherwise unbreakable string to prevent text from overflowing its line box.

Try it

Note: In contrast to word-break , overflow-wrap will only create a break if an entire word cannot be placed on its own line without overflowing.

The property was originally a nonstandard and unprefixed Microsoft extension called word-wrap , and was implemented by most browsers with the same name. It has since been renamed to overflow-wrap , with word-wrap being an alias.

Syntax

/* Keyword values */ overflow-wrap: normal; overflow-wrap: break-word; overflow-wrap: anywhere; /* Global values */ overflow-wrap: inherit; overflow-wrap: initial; overflow-wrap: revert; overflow-wrap: revert-layer; overflow-wrap: unset; 

The overflow-wrap property is specified as a single keyword chosen from the list of values below.

Values

Lines may only break at normal word break points (such as a space between two words).

To prevent overflow, an otherwise unbreakable string of characters — like a long word or URL — may be broken at any point if there are no otherwise-acceptable break points in the line. No hyphenation character is inserted at the break point. Soft wrap opportunities introduced by the word break are considered when calculating min-content intrinsic sizes.

The same as the anywhere value, with normally unbreakable words allowed to be broken at arbitrary points if there are no otherwise acceptable break points in the line, but soft wrap opportunities introduced by the word break are NOT considered when calculating min-content intrinsic sizes.
