How to Create a Contact Form using HTML5, CSS3 and PHP | Tangled in Design Personally, I feel it is important to be aware of the [positive] impact HTML5 will have on forms and the way they will function in years to come. Realistically, we can’t implement all of the new features today, but you don’t want to be lagging behind the rest of the industry when these features finally become widely supported. Having said that, this tutorial will be focusing on the new HTML5 features that are already supported by all the major browsers, or that at least employ graceful degradation for the browsers that are still trying to play catch up. 1. The Design First of all, this is not a Photoshop tutorial. 2. Now we have a design to work towards, we’re going to form the structure of the contact form using HTML5. Doctype Okay, now we’ve got our blank PHP document, let’s start with the appropriate doctype, which is a lot simpler in HTML5 than previous versions to say the least! <! Yep, that’s right. Just to compare, here’s the doctype for XHTML; <! Structure <! That’s right. The Form 3. <?
Learning from Twitter An issue popped up on Twitter this past week that caused the web site to be generally unusable for many users. It appears as if attempts to scroll were unbearably slow and caused the site to be unresponsive. The Twitter team investigated and determined that if they reverted the version of jQuery that they used back to 1.4.2 from 1.4.4 the site would be responsive again. After more investigation they determined that the code that was slow was doing a contextual selector search for an item by class name, for example: $something.find(".class"). So – what happened? However, as with every performance change, while some things get way faster some things can also get slower. What’s interesting here is that we’ve been using querySelectorAll for our default selector engine in jQuery for quite some time now (doing $(‘.class’) would use querySelectorAll). This brings up the important point: Just how much faster is getElementsByClassName compared to querySelectorAll? So. Comments are closed.
Parallax Scrolling and Its Usage in Web Design The parallax effect, also called parallax scrolling, is a special technique used in computer graphics at first, where background images move by the camera slower than foreground images. This is the actual concept where websites with parallax scrolling started. It was widely used in the gaming industry more than 10-15 years ago and it is still used today in different domains. In the past years the parallax effect started to be used widely in web design. Its popularity went through the clouds when Nike redesigned their website based on this concept. The design concept started to be used because it is actually quite cool. Parallax Scrolling Examples Although this is usually the case, utilizing the parallax scrolling effect doesn’t have to limit you to a fake 3D effect. When they see it for the first time, people use to think that the effect is nice. Performance Issues Although the effect looks brilliant, there are some downsides to it, such as the performance issues. New age technologies
Don’t use ID selectors in CSS | screwlewse.com Posted on: July 28, 2010 / Lately I have been testing out performance among css styles and I found that some of my very smart friends, started asking,”why aren’t you testing using IDs for the unique sections of the page?”. This wasn’t a hard answer: The element is not re-usable on that page.This is the begining of a downward sprial into specificityUsually, IDs refer to something very specific, and abstracting would be toughAny performance gains picked up by using id, is negated by adding any other selector to the left fo that id Lets delve into each of these issues at more length The element is not re-usable on that page: IDs are programmer’s equivalent to singletons. This is the beginning of a downward spiral into specificty: There are two main ways of overriding in css. The cascade: (anything further down the css, can overwrite the previous css rules)Specificity: the idea of creating weight by using weighted selectors. Above is real code from one of my own work from 2005. On the other hand:
jQuery.parallax Download git clone github.com/stephband/jparallax Instantiation jQuery( '.parallax-layer' ).parallax( options ); What does jquery.parallax do? jParallax turns nodes into absolutely positioned layers that move in response to the mouse. With a bit of CSS you can either set up windows to see these layers through, or leave them free to roam about. The diagram on the right illustrates what jParallax does to the html: and here's a demonstration with some images: More demos demos/index.html demos/stalkbuttons.html - multiple parallax. demos/remotecontrol.html - parallax by remote control. demos/thumbnails.html - beautiful interactive thumbnails. demos/target.html - demonstrates how smoothly jParallax handles window resizing. Using jParallax The default behaviour of jParallax is to show the whole width of a layer in response to the mouse travelling the whole width of the mouseport. There are various ways to style jParallax effectively. Options Layer Options Events

Masked Input Plugin First, include the jQuery and masked input javascript files. Next, call the mask function for those items you wish to have masked. jQuery(function($){ $("#date").mask("99/99/9999"); $("#phone").mask("(999) 999-9999"); $("#tin").mask("99-9999999"); $("#ssn").mask("999-99-9999");}); Optionally, if you are not satisfied with the underscore ('_') character as a placeholder, you may pass an optional argument to the maskedinput method. Optionally, if you would like to execute a function once the mask has been completed, you can specify that function as an optional argument to the maskedinput method. You can now supply your own mask definitions. jQuery(function($){ $.mask.definitions['~']='[+-]'; $("#eyescript").mask("~9.99 ~9.99 999");}); You can have part of your mask be optional. jQuery(function($){ $("#phone").mask("(999) 999-9999? If your requirements aren't met by the predefined placeholders, you can always add your own. jQuery(function($){ $("#phone").mask("#hhhhhh");});
