Can you explain the contrast between a control's style being set to display: none versus display: block?
Can you explain the contrast between a control's style being set to display: none versus display: block?
When it comes to HTML elements, the display property plays a crucial role in determining how they appear on the web page. By using block and none, you can control whether an element is shown or hidden. For more information on the display property and its various options, check out this resource here.
none: The element will not be visible on the page.
block: The element will be displayed as a block-level element, similar to paragraphs and headers.
Hidden from view; - This element is present in the document object model (DOM), but it is not visible and does not occupy any space, unlike using visibility:hidden.
Block display mode; - When an element is set to display as a block, it occupies the entire available width and does not allow other elements to be positioned beside it. For example, a div element.
These two CSS properties serve different purposes.
display: none completely removes the element from the webpage, not occupying any space on the screen while still being present in the source code. (The element will not be visible)
display: block causes the element to fill the entire width of its container. (There will be a line break before and after the element)
Are you inquiring about a CSS property perhaps? This particular property is commonly used to show or hide DOM elements.
The CSS property in question is 'display', with possible values of 'none', 'block', and more.
For more information, you can refer to the following resource: CSS Display as recommended by
block
Objects are rendered as block elements.
none
The element is not rendered, having no effect on layout. The document is displayed as if the element doesn't exist, including all child elements.
inline
By default, the object is rendered as an inline element based on content dimensions.
list-item
Specific to Internet Explorer 6 and later, objects are rendered as block elements with a list-item marker.
table-header-group
The object is rendered as a tHead, where the table header is always displayed before other rows and row groups, and after any top captions.
table-footer-group
The object is rendered as a tFoot, with the table footer always displayed after other rows and row groups, and before any bottom captions.
inline-block
Objects are rendered inline, but their contents are treated as block elements. Adjacent inline elements are displayed on the same line, if space permits.
Visibility:hidden; hides the element from view, while Visibility:visible; makes it visible on the screen.
When using display:none, there is a subtle detail to keep in mind: if you add a child div dynamically to a parent div and explicitly set the visibility property of the child to "visible", the parent's visibility property will only affect the parent itself; the child will remain visible regardless of the parent's setting.
In situations where the visibility of the parent and child elements are controlled by different style rules, applying display:none to the parent will hide all of its children - even if each element has its own styling properties.
When an element has a display property set to "none", it means that the element is completely hidden from view and will not be visible in the example.
On the other hand, when the display property is set to "block", the element is displayed as a block similar to paragraphs and headers. Blocks have whitespace above and below them and do not allow any HTML elements to appear next to them unless specified otherwise.
By using the "display: none" property, you can effectively hide the control on a webpage and prevent it from being rendered.
On the other hand, setting the display property to "block" will show the element on the web page at a block level.
When you use display:none, it will hide the contents. For example, if you apply it to a div element, the width and height of the div will also be hidden. If you want to show the contents, you can use display:block instead.
