HTML Coding ConventionsWeb developers are often uncertain about the coding style and syntax to use in HTML.Between 2000 and 2010, many web developers converted from HTML to XHTML.With XHTML, developers were forced to write valid and 'well-formed' code.HTML5 is a bit more sloppy when it comes to code validation.Be Smart and Future ProofA consistent use of style makes it easier for others to understand your HTML.In the future, programs like XML readers may want to read your HTML.Using a well-formed-'close to XHTML' syntax can be smart. Avoid Long Code LinesWhen using an HTML editor, it is inconvenient to scroll right and left to read the HTML code.Try to avoid code lines longer than 80 characters.Blank Lines and IndentationDo not add blank lines without a reason.For readability, add blank lines to separate large or logical code blocks.For readability, add two spaces of indentation. Do not use the tab key.Do not use unnecessary blank lines and indentation.
Purists would say that you don't need any tools - you can write HTML5 code with a biro and a bit of paper if you wish - but others prefer tools such as Adobe's Dreamweaver, which gained an HTML5.
It is not necessary to indent everyelement. A viewport element gives the browser instructions on howto control the page's dimensions and scaling.The width=device-width part sets the width of the page to follow the screen-width of the device (which will vary depending on the device).The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.Here is an example of a web page without the viewport meta tag, and the same web page with the viewport meta tag.
J.saer 14-Nov-Nov-14 10:16Why (developers?) insist so much in using HTML/Javascript for EVERYTHING?HTML pages, of course have their place at the Apps Universe, but. Why it seems that so many people try to convice the rest of the people that are GOOD for everything?Web applications are unsecure, are limited to the web browser in use allow them to do. They are NOT pixel perfect. They behave different on every browser and this is going to be always in this way. And we all know about this.
On the other hand. We have JavaScript.a hard to read/debug language accessing a different DOM for every browser. We are forced to overuse computational resources just because the browser must be running either for a Hello World page or something bigger.Operating Systems exist for a reason, System Calls, API exists for a reason, they do their job.
They do it very well. We have free tools to using them.
And through them we have full control of the hardware, and the user interface. And in this way we can honor and take full advantage of the target device. It is a little harder?
Who saids that developing good, usable, solid reusable software it's a trivial thing? Rabb Moshe Plotkin 3-Apr-12 18:183-Apr-12 18:18B'HYou have created the perfect virus peatry dish.You have given every malicious website the ability to totally control the users devices and secretly invade and potentially violate the lives of your unsuspecting users.The regular android web browser DOES allow web pages using javascript to access both the camera and the gps. But first it asks permission from the user, and it goes through great pains to limit the reach of that functionality so that it can not be used to harm the device or the life the the user. Your statement is true, and lots of articles already mentioned this weakness of JavaScript interface on Android WebVierw component.But, the question is 'I never plan to create a general purpose web browser'. In my project, I preset the home page to my 'Pollution Enforcement Site', and pre-bookmark a few related project sites. Actually, we should try to prevent or block our users to browser non project related sites (which may cause un-expected problems like namespace collision, flash, security.???).
Building Android Apps With Html Css And Javascript Source Code
Gcstang 26-Mar-Mar-12 12:45The concept is pretty neat, however I don't see it as a feasible alternative to releasing a real application due to the fact that you have to download the application from a site outside your own and the browser doesn't have the branding associated with my company/application.It would be great if the application project was released and could be deployed as an application with a single URL where my application was hosted. Maybe it's not the group you're targeting but I just see that it could have more potential than just another browser that I have to externally plug URL's into, kind of hard to sell that to customers.But I really like the idea and features, NICE Job!
How To Write Html5 Code For Header
Maybe I'm still an old fashion web developer. Basically, I sell a 'solution' which includes front-end, back-end, and database to meet my customer needs, rather than copies of apps for sale.Today, we (web developers) implement our solutions with different databases (MySQL, MS SQL.) and different server side languages (PHP,.NET.), but do we actually own any browsers with our company's brand or logo?There is a tool called 'PhoneGap' does exactly what you want. However, it requires Android SDK, some knowledge about Android programming, Android Market (Google Play), and more.
