Lazy loading (also known as asynchronous loading) is a technique used in computer programming, especially web design and web development, to defer initialization of an object until it is needed. It can contribute to efficiency in the program's operation if properly and appropriately used.
The header text of the webpage is firstly rendered before the Bootstrap CSS files. The issue was documented in an article named "Flash of Unstyled Content". [4] At first, FOUC appeared to be a browser problem unique to Internet Explorer but later became apparent in other browsers, [5] [6] and has since been described as "a Safari epidemic". [7]
In computer programming, lazy initialization is the tactic of delaying the creation of an object, the calculation of a value, or some other expensive process until the first time it is needed. It is a kind of lazy evaluation that refers specifically to the instantiation of objects or other resources.
To demonstrate specificity Inheritance Inheritance is a key feature in CSS; it relies on the ancestor-descendant relationship to operate. Inheritance is the mechanism by which properties are applied not only to a specified element but also to its descendants. Inheritance relies on the document tree, which is the hierarchy of XHTML elements in a page based on nesting. Descendant elements may ...
Lazy evaluation can also lead to reduction in memory footprint, since values are created when needed. [19] In practice, lazy evaluation may cause significant performance issues compared to eager evaluation. For example, on modern computer architectures, delaying a computation and performing it later is slower than performing it immediately.
JavaScript code can use the Document Object Model (DOM), provided by the HTML standard, to manipulate a web page in response to events, like user input. Using a technique called AJAX , JavaScript code can also actively retrieve content from the web (independent of the original HTML page retrieval), and also react to server-side events as well ...
Angular Material includes a variety of UI components such as buttons, cards, dialogs, grids, and form controls. These components are designed to be customizable and easy to integrate into Angular applications. Additional features of Angular Material include support for responsive design, theming, and accessibility.
[5] Less is inspired by Sass. [6] [3] Sass was designed to both simplify and extend CSS, so things like curly braces were removed from the syntax. Less was designed to be as close to CSS as possible, and as a result existing CSS can be used as valid Less code. [7] The newer versions of Sass also introduced a CSS-like syntax called SCSS (Sassy CSS).
