Tables 17.1 Introduction to tables This chapter defines the processing model for tables in CSS. Part of this processing model is the layout. For the layout, this chapter introduces two algorithms; the first, the fixed table layout algorithm, is well-defined, but the second, the automatic table layout algorithm, is not fully defined by this specification. For the automatic table layout algorithm, some widely deployed implementations have achieved relatively close interoperability. Table layout can be used to represent tabular relationships between data. In a visual medium, CSS tables can also be used to achieve specific layouts. Authors may specify the visual formatting of a table as a rectangular grid of cells. Example(s): Here is a simple three-row, three-column table described in HTML 4: <TABLE><CAPTION>This is a simple 3x3 table</CAPTION><TR id="row1"><TH>Header 1 <TD>Cell 1 <TD>Cell 2 <TR id="row2"><TH>Header 2 <TD>Cell 3 <TD>Cell 4 <TR id="row3"><TH>Header 3 <TD>Cell 5 <TD>Cell 6 </TABLE> top
Enclosing Float Elements | Floats | HTML & CSS Workshop | Gary Turner web development Developers who are new to css, or those who work primarily in IE, run into a vicious “bug” in Firefox and other modern browsers. Their backgrounds disappear, or their borders do—but everything's fine in IE. The gnashing of teeth is heard throughout the land. The truth is, there's a reason for the behavior, and IE has screwed up again. In this demo, there are two ways to see what's going on, IE's way, and the right way. IE7 has internalized many of the IE6 bug work-arounds. Basic Non-Enclosed Float Notice that in the first box, the float element extends beyond the parent div. On a side note, IE does not properly handle collapsed margins when an element has layout. Now is the time for all good men to come to the aid of their country. This is non-float content. Using The Overflow Property If the parent element has an overflow: value other than the default “visible”, the height of the element will be sufficient to contain child floats. Using The Display Property And so is this.
Top 10 Things to Know about TypeScript Introduction TypeScript is a superset of JavaScript that provides typed nature to your code. TypeScript can be used for cross-browser development and is an open source project. This article is intended to give you a quick overview of the top 10 features of this new scripting language. 1. TypeScript code consists of plain JavaScript code as well as certain keywords and constructs specific to TypeScript. The above code uses TypeScript specific keywords such as class and data types such as number and string. var Customer = (function () { function Customer() { } Customer.prototype.addCustomer = function () { return 0; }; return Customer; })(); As you can see this is just the plain JavaScript and can be used in any browser that understands JavaScript. 2. When you declare any variable in JavaScript you typically do so using var keyword without specifying any particular data type for the variable. window.onload = function () { var data = 10; alert(data); data = "hello world"; alert(data); } 3.
Differences Between CSS2.1 and CSS3+ Most of us know that with the introduction of what we customarily call “CSS3″1, there have been changes and additions to CSS, compared to what we had in CSS2.1. Putting all cross-browser issues aside, I thought it would be nice to be able to document all these changes into a single post and keep it up to date. So if you want a list of everything that’s been introduced into the CSS spec since CSS2.1, here it is. New Properties Following is a list of CSS properties that were not defined in the CSS2.1 specification. New Values Properties from CSS2.1 have new values added to them in CSS3. New Selectors Following is a list of selectors introduced in CSS3. Other Miscallaneous New Features Other new features not part of CSS2.1 include: @font-faceMedia QueriesKeyframe animations using @keyframesConditional styles using @supportsNamespacing using @namespaceRegionsFilters Features Still in Flux The lists above aren't exhaustive.

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky Wednesday, October 08, 2003 Ever wonder about that mysterious Content-Type tag? You know, the one you're supposed to put in HTML and you never quite know what it should be? Did you ever get an email from your friends in Bulgaria with the subject line "???? I've been dismayed to discover just how many software developers aren't really completely up to speed on the mysterious world of character sets, encodings, Unicode, all that stuff. But it won't. So I have an announcement to make: if you are a programmer working in 2003 and you don't know the basics of characters, character sets, encodings, and Unicode, and I catch you, I'm going to punish you by making you peel onions for 6 months in a submarine. And one more thing: In this article I'll fill you in on exactly what every working programmer should know. A Historical Perspective The easiest way to understand this stuff is to go chronologically. And all was good, assuming you were an English speaker. Unicode Hello Encodings Right?
Creating an image map from SVG | David Lynch I was asked how I made the map in my examples earlier. I wrote a small script to do it. (The script is quite limited – I only made it complete enough to handle the SVG files I was using. Others might break it. Example! Wikipedia is good for this, and has provided me with the example file I’ll use, a map of the USA. My example file is filled with all sort of crud that isn’t a definition of state boundaries, though, so I need to get just that. So I run my script: svg2imagemap.py Map_of_USA_with_state_names.svg 960 593 States (The “960 593” is the size of the image I’m creating from the SVG file.) This creates an html file named [svg name].html, so Map_of_USA_with_state_names.html. And we get: A map of the USA. Just to disclaim again: That script is unlikely to be immediately useful for any particular SVG image. One last time: I make no guarantee of this script working on an arbitrary SVG file.

Can I use... Support tables for HTML5, CSS3, etc Writing Testable Frontend Javascript Part 1 – Anti-patterns and their fixes | Shane Tomlinson This is the first of a two part introduction to writing testable Javascript UI code. The first article presents a basic sample application containing several common anti-patterns and their solutions.In the second article, the application will be refactored using the described techniques, a simple XHR mock will be presented, and add a test suite will be added to help future developers maintain the code. Front end development comes with a set of challenges that are rarely discussed in articles about unit testing. Self initialization, encapsulated logic, DOM event handlers, XHR requests, and nested callbacks all make testing difficult. Fortunately, writing front end code so that it can be tested is straight forward, but it does require a little knowledge and thought. Common coding practice – Easy to understand, difficult to test While short, this contrived example uses several common anti-patterns. Anti-patterns that make this application difficult to test Externalize all Javascript ... ...
