Media types 7.1 Introduction to media types One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'page-break-before' property only applies to paged media). On occasion, however, style sheets for different media types may share a property, but require different values for that property. Online CSS Unminifier - Peter Coles You may be aware of js unminifiers or beautifiers (such as jsbeautifier).

Permissions In FreeBSD, every file and directory has an associated set of permissions and several utilities are available for viewing and modifying these permissions. Understanding how permissions work is necessary to make sure that users are able to access the files that they need and are unable to improperly access the files used by the operating system or owned by other users. This section discusses the traditional UNIX® permissions used in FreeBSD. For finer grained file system access control, refer to Section 14.9, “Access Control Lists”. In UNIX®, basic permissions are assigned using three types of access: read, write, and execute. These access types are used to determine file access to the file's owner, group, and others (everyone else).

Safari Web Content Guide: Configuring the Viewport Safari on iOS displays webpages at a scale that works for most web content originally designed for the desktop. If these default settings don’t work for your webpages, it is highly recommended that you change the settings by configuring the viewport. You especially need to configure the viewport if you are designing webpages specifically for iOS.

Before configuring the viewport, you need a deeper understanding of what the visible area and viewport are on iOS. If you are already familiar with the viewport on iOS, read “Using the Viewport Meta Tag” for details on the viewport tag and “Viewport Settings for Web Applications” for web application tips.
