Activating Browser Modes with Doctype

Activating Browser Modes with Doctype
In order to deal both with content written according to Web standards and with content written according to legacy practices that were prevalent in the late 1990s, today’s Web browsers implement various engine modes. This document explains what those modes are and how they are triggered. Summary for the Impatient The main conclusion to draw from this article is that you should start all your HTML documents (i.e. anything that gets served as text/html ) with <!DOCTYPE html> as the first thing in the source. If you want to take extra care to make sure that users of IE8, IE9 or IE10 cannot press a button that makes your site regress as if it was being viewed in IE7, either configure your server to send the HTTP header X-UA-Compatible: IE=Edge for text/html or put <meta http-equiv="X-UA-Compatible" content="IE=Edge"> in the head of your HTML documents (before any scripts). The Scope of This Document The Modes Here are the various modes: Common Modes for text/html Content Quirks Mode Chrome Quirks

How to construct a web developer in twelve months | Graceful Exits A friend got in touch recently to ask for help on making a career change into web development. They were involved in technology some fifteen years ago—more than me in a lot of ways—but appreciated that things had changed almost beyond recognition, so they would at least need to upskill and were worrying if they should concentrate on retraining and getting an academic qualification. In effect, they were giving themselves maybe twelve months of spare time to become at least savvy enough for an entry-level job in the industry, and wanted to know if I could advise them. I didn't initially see how I could possibly help them. After all, in terms of web development I'm almost completely self-taught, and a lot of that has been through processes of osmosis and curiosity rather than through any particular grand plan. Why not blog about how you might go about rebuilding yourself over a year, and post a link in the comments?

List of HTTP headers HTTP header fields are components of the message header of requests and responses in the Hypertext Transfer Protocol (HTTP). They define the operating parameters of an HTTP transaction. General format[edit] Field names[edit] A core set of fields is standardized by the Internet Engineering Task Force (IETF) in RFC 2616 and other updates and extension documents (e.g., RFC 4229), and must be implemented by all HTTP-compliant protocol implementations. The permanent registry of headers and repository of provisional registrations are maintained by the IANA. Non-standard header fields were conventionally marked by prefixing the field name with X- .[2] However, this convention became deprecated in June 2012 due to the inconveniences it caused when non-standard headers became standard.[3] A prior restriction on use of Downgraded- has also since been lifted.[4] Field values[edit] A few fields can contain comments (i.e. in User-Agent, Server, Via fields), which can be ignored by software.[5] [edit]
