It is essential for a Developer to understand that the term web browser has expanded to include HyperText Transfer Protocol Requests (HTTP) from five different categories of client devices.
We must consider Desktop, Tablet, Mobile, TV and Gaming Web Browsers when coding our web pages in HyperText Markup Language (HTML). An essential component of this development is the effective use of Cascading Style Sheets (CSS).
The web browser builds a request for a web page and sends it to the web server. This request is formatted using the HyperText Transfer Protocol (HTTP), which lets the web server know which file is being requested. When the web server receives the HTTP request, it retrieves the requested file from the disk drive. This file contains the HTML (HyperText Markup Language) for the requested page. Then the web server sends the file back to the browser as part of an HTTP response. When the web browser receives the HTTP response, it renders (translates) the HTML into a web page that is displayed in the browser.
The Apple iCloud News RSS feed to the right of this paragraph is a "feed" from the Apple Support Database URL (Uniform Resource Locator) http://rss.support.apple.com/icloud. Rather than create a link to this website, I placed an HTML "iframe" that places a live feed of a maximum of twenty news items in a widget. This is a good way to feed any live data to your website that is pertanent to your content. The "iframe" has a scroll bar. Place your cursor within the widget to view up to twenty news stories pertaining to iCloud technology. Click on any of the blue links. This will open up the article in a new window. When the users closes that window, they will return to your webpage.
A Web Browser is a software program used by client devices to request web pages written in HTML from web servers that host websites. Examples of desktop browsers are Google Chrome, Mozilla Firefox, Opera, Apple Safari, Internet Explorer & Maxthon - a newcomer to the field of browsers. Maxthon is a multi-platform cloud browser that has a built-in Flash component that alleviates the inability of Macs to process Flash files.
