Page last changed today Conditional comments only work in IE, and are thus excellently suited to give special instructions meant only for IE. They are supported from IE 5 up until IE9 (inclusive). Older IE versions frequently need some extra CSS in order to show your pages right. Conditional comments are the best way to add this CSS, since the system is explicitly designed for this use case.
If you need special styles for IE10 or up you’ll have to find another method, since conditional comments were disabled in IE10. However, these versions are much less buggy than the earlier ones. Conditional comments work as follows: <! Their basic structure is the same as an HTML comment (<! Below I added a lot of conditional comments that print out messages according to your IE version.

As a hater of horizontal scrollbars, I’ve always been intrigued by layout design that resizes with browser windows.
And as a lover of usability and accessibility, I have a keen interest in layouts that resize with text resizing. So when fluid/liquid and elastic design became the trendy web topics in the mid 2000s, I experimented alongside every other bandwagon jumper. What I discovered was 1) I still suck terribly at math 2) the lazy designer in me much prefers the “known” parameters of fixed design and 3) while both elastic and fluid design were heading in the right direction, they had their limitations: Without setting max-width (which isn’t supported in < IE7) values, line-lengths can become unreadable in fluid layouts.Elastic designs don’t resize unless text is resized. Using both fluid and elastic together was an acceptable compromise, but the design “flexibility” was limited to size … font size, image size and layout size.

NOTE: This is a bit of a mental health warning for web design beginners and could save you some time and some unnecessary wrinkles when you’re starting to code your own web pages. When I first began coding websites using HTML and CSS, I remember running into endless problems with the way my CSS styles would render in web browsers.
Countless hours were wasted while I tried to get to the bottom of why my header was 40 pixels wider than I wanted it to be, or why I always got that annoying dashed line around my links when I clicked on them. Grrrr! Admittedly, I had no idea what I was doing back then and I was going through the extremely painful process of teaching myself web design whilst actually running a web design business.

If you have shopped online or signed up for emails from a business, chances are you receive e-blasts on a regular basis.
They are eye-catching emails sent out to a group of contacts to inform or create a call to action. But don’t just start emailing everyone in your address book or you may turn away customers. Here’s what I suggest: Find an e-blast service to manage contacts, analyze statistics on the effectiveness of your message, prevent SPAM, conduct surveys or polls, and create interesting e-blasts. Build up your contact base and make sure to categorize them well for optimal targeting. iContact offers a sign-up form you can create with your own custom fields. Keep your e-blasts brief, yet informative and interesting. Make sure you highlight the call to action. Test the e-blast prior to sending. Also test for spam ratings. Respect unsubscribe requests.

Holy Javascript Libraries, Batman! In case you’re keeping score, Adobe began shipping Dreamweaver CS5.5 less than two weeks ago with support for jQuery and jQuery Mobile. But, the versions included in Dreamweaver, jQuery 1.5 and jQuery Mobile 1.0a3, are already out of date! Because before you could even get your copy installed, the jQuery team released a significant upgrade to the core jQuery library – version 1.6. Along the way, the jQuery Mobile framework has also been updated to version 1.0a4, which includes several important bug fixes. So, if you are a Dreamweaver user and you want to develop jQuery Mobile sites and applications with these updated versions of the libraries, what are you supposed to do?

Mi piace: Mi piace Caricamento... Introduzione alla programmazione web per designer. Per un designer la programmazione web dovrebbe essere affrontata con molta serenità. La difficoltà maggiore sta nella differenza esistente tra il design e la programmazione. Il design si basa sulla soggettività, le emozioni e l’interiorità.
La programmazione, al contrario, sull’oggettività, le azioni e gli effetti esteriori di queste ultime. Tale differenza si può capire meglio se si considera il design come espressione di un pensiero complesso, laddove la programmazione è l’espressione di un pensiero binario. Nel design una scelta può essere valutata sotto diversi aspetti, mentre in programmazione ci sono solo due cose da considerare: la scelta funziona o non funziona.
