The Cascading Style Sheets (CSS) specification describes how elements of web pages are displayed by graphical browsers. Section 4 of the CSS1 specification defines a "formatting model" that gives block-level elements—such as p and blockquote—a width and height, and three levels of boxes surrounding it: padding, borders, and margins. [4]
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 ...
The framework aims to alleviate the overhead associated with common activities used in web development. For example, many frameworks provide libraries for database access, template processing and session management, and often promote code reuse. Though they often target development of dynamic websites they are also applicable to static websites.
Python's syntax is simple and consistent, adhering to the principle that "There should be one— and preferably only one —obvious way to do it." The language incorporates built-in data types and structures, control flow mechanisms, first-class functions , and modules for better code reusability and organization.
Both Sass and Less are CSS preprocessors, which allow writing clean CSS in a programming construct instead of static rules. [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 ...
Complexity is managed both at the design stage (how the project is architectured) and at the development stage (by having simpler code). If the coding is kept basic and simple then the complexity will be minimised. Very often this is keeping the coding as 'physical' as possible - coding in a manner that is very direct and not highly abstract.
Style may be chosen specifically for a piece of content, see e.g., color; scope of parameters Alternatively, style is specified for CSS selectors, expressed in terms of elements, classes, and ID's.
A CSS framework is a library allowing for easier, more standards-compliant web design using the Cascading Style Sheets language. Most of these frameworks contain at least a grid . More functional frameworks also come with more features and additional JavaScript based functions, but are mostly design oriented and focused around interactive UI ...
