==== Class for 2013-03-25: Backend web development ====
+
==== Class for 2013-09-16: CSS3 ====
This class was all about the seedy underbelly of web development: the backend!
+
We'd covered CSS3 before, but in the context of a mockup. We looked further into CSS3 with a demonstration of what the new technologies are, how to make the most of them, and how to make sites using them look good in less capable browsers.
  
I know we already have a [[Backend_web_dev_in_Ruby_on_Rails|backend class here at Noisebridge]], but this one was tailored toward frontend developers wanting to get a taste of how things come together. We spent the first half talking about PHP, then moved onto a Rails, a more complex example.

Here are the steps used for class preparation:

==== Class for 2013-09-09: HTML5 elements ====
 +
We took an entertaining (in my opinion) look through [http://jeffreyatw.com/static/frontend/series4/class16/html.zip this page containing every currently valid HTML element]. Many of them are considered "HTML5" elements, but that's just because they're relatively new.

===== THE EASY WAY: =====
+
==== Class for 2013-08-26: ClassName Swap, Language Review, RTFM, by Garrett Smith ====
If you would like to follow along and are on Windows or OS X, the easiest option is to run a virtual machine:
+
* Install [https://www.virtualbox.org/wiki/Downloads VirtualBox AND the Extension Pack]
+
* [http://jeffreyatw.com/static/frontend/series3/class20/Ubuntu.ova Download this preconfigured Ubuntu virtual machine (1.82GB)]
+
* Double-click the .ova file. You might want to check the "reinitialize the MAC address" step.
+
* Start the machine after installation and you're all set!
+
* System username and password are both "frontend". Feel free to change them if that's uncomfortable.
+
  
===== THE HARDER WAY: =====
+
===== Lesson: CSS ClassName Swap =====
If you don't want to use a virtual machine. I haven't tried these myself, so I can't profess as to how easy or hard it is.
+
By changing an element's <code>className</code> multiple styles can be changed at one time.  
  
On Linux, you'll need to follow these steps:
+
Using the descendant selector, and changing the <code>className</code> of an ancestor element, multiple elements can be updated simultaneously, with a modicum of highly efficient code.
* http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
+
* https://help.ubuntu.com/community/ApacheMySQLPHP
+
  
On Windows or Mac OS X:
+
For Styles, replace a loop that applies styles to descendants by adding a class token to the nearest common ancestor ([http://jibbering.com/faq/notes/code-guidelines/descendant-sel.html example], [http://jibbering.com/faq/notes/code-guidelines/#design explanation]).
  
* Start with RailsInstaller: http://railsinstaller.org/
+
====== Calculating Selector's Specificity ([http://www.w3.org/TR/CSS2/cascade.html#specificity CSS 2.1]). ======
* And for PHP:
+
The classname swap example leverages the fact that class selectors (e.g. <code>.foo</code>) have higher specificity than element selectors (e.g. <code>tr</code>).
** Mac: http://www.mamp.info/en/index.html
+
** Windows: http://www.wampserver.com/en/
+
  
===== THE HARDEST WAY: =====
+
CSS Selector specificity is determined four numbers, a-b-c-d, in a number system with a large base.
Install Apache, PHP, RVM, Ruby, and Rails individually. Good luck!
+
<blockquote cite="http://www.w3.org/TR/CSS2/cascade.html#specificity">
 +
    count 1 if the declaration is from is a 'style' attribute rather than a rule with a selector, 0 otherwise (= a) (In HTML, values of an element's "style" attribute are style sheet rules. These rules have no selectors, so a=1, b=0, c=0, and d=0.)
 +
    count the number of ID attributes in the selector (= b)
 +
    count the number of other attributes and pseudo-classes in the selector (= c)
 +
    count the number of element names and pseudo-elements in the selector (= d)
 +
</blockquote>

===== RTFM =====

Unschooling and autodidacticism; an Intro to [http://www.catb.org/jargon/html/R/RTFM.html RTFM], RTFFAQ, and SFTW.

Understanding defines the difference between the followers, who resort to mystical incantations or convoluted DOM libraries to do the work for them, and those who can implement project requirements, as specified, with [http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&ved=0CDMQtwIwAQ&url=http%3A%2F%2Fvimeo.com%2F13702091&ei=XN8eUtSTDuaaiQfo0oGwAw&usg=AFQjCNGkkzJmJXyBpBXpyVaHkpmsN1IUcQ&sig2=Ws2-2YmQJkgYwKCd7Bfx-Q&bvm=bv.51495398,d.aGc clean code (Vimeo)]. And not downloading free scripts off dynamic drive or [ jQuery], copying, or programming by observation.
  
==== Class for 2013-03-18: Version control (Git) and the command line ====
+
When misunderstandings or debates arise, and that happens fairly often, it is important how to find the answer using STFW and RTFM,
This class was a general overview on version control and the command line. I'd taught how to use an FTP client to upload files to the web, but the truth is that most developers don't do that anymore - rather, they collaborate with their peers by using version control systems, which allows them to keep track of their work in a reliable fashion and push it to the web.
+
and when that fails, how (and where ([https://groups.google.com/forum/#!forum/comp.infosystems.www.authoring.html CIWAS], [https://groups.google.com/forum/#!forum/jsmentors JSMentors], [https://groups.google.com/forum/#!forum/comp.lang.javascript c.l.js], [https://groups.google.com/forum/#!forum/comp.infosystems.www.authoring.html ciwah]) to ask a [http://www.catb.org/esr/faqs/smart-questions.html smart question].
  
Again, this class wasn't about web development per se - it was just an important introduction to using the command line to work with Git, one of the most popular version control systems. Everyone created their own repository and checked in their work.

We signed up for a free account at [https://github.com/ GitHub] and installed [http://git-scm.com/ Git]. Those on Windows installed [http://msysgit.github.com/ Git for Windows] (all default options are fine).

==== Class for 2013-03-11: Old vs. new: progressive enhancement and browser testing ====
+
==== Class for 2013-08-12: More useful jQuery plugins ====
We talked about progressive enhancement - a practice where websites are created in a layered way that makes them accessible and cross-browser friendly. We looked at [http://jeffreyatw.com/static/frontend/series3/class19/sites.zip two versions of an example site] and demonstrated how one is outdated, and the other adheres to progressive enhancement principles. We've touched on these concepts throughout the whole class, but in this class we focused on why they're important, and what could happen if you DON'T adhere to them.
+
 
+
This segued nicely into a talk about browser testing - how to do it and what to look out for.

We took [http://jeffreyatw.com/static/frontend/series3/class17/blog.zip this blog] and turned it into a mobile-accessible website via the use of media queries. We also talked about the rest of the world of the mobile web: user agent strings, frameworks like jQuery Mobile and Sencha Touch, and the future of HTML5/CSS3 in mobile website and app development.

==== Class for 2013-08-05: Sign-up forms ====
We continued working on [http://jeffreyatw.com/static/frontend/series3/class13/lecture.zip our site] and added a sign-up form, with validation, inside the modal. We used the [http://bassistance.de/jquery-plugins/jquery-plugin-validation/ jQuery Validation plugin]. This is a very common request from clients and it comes in handy to know all the tips and tricks of forms and validation, and what new HTML5 elements can provide.

==== Class for 2013-07-29: Modals and menus ====
We went back to the [http://jeffreyatw.com/static/frontend/series3/class13/noiseco.zip "professional" site we'd put together a number of weeks ago] and added more functionality to it with some jQuery plugins. We first made a dialog box - or a "modal" - pop up when you click the sign up buttons. We did this by introducing [http://jqueryui.com/ jQuery UI] to make common web development tasks easier. We also add some dropdown functionality to our menus using pure CSS, but this can be done using jQuery UI or [http://twitter.github.com/bootstrap/ Bootstrap] as well.

We talked about Asynchronous JavaScript and XML, a technology that allows us to talk to a server without leaving the page. jQuery makes this extremely easy. We added AJAX functionality to [http://jeffreyatw.com/static/frontend/series3/class10/lecture.zip our app we've been building on]. We used this [http://jeffreyatw.com/static/frontend/class9/tweet.php.zip PHP file] to test it out.

We talked about file transfer - not only uploading files using FTP, but using the web browser to get and send information via forms and other methods (an overall talk about HTTP GET/POST).
+
We continued learning about jQuery by focusing on [http://jeffreyatw.com/static/frontend/series4/class10/lecture.zip the example we saw last week]. We added functionality to it that made it seem more like the real thing.
  
We downloaded and installed [http://filezilla-project.org FileZilla] and signed up for a [https://nearlyfreespeech.net NearlyFreeSpeech.NET] hosting account.

We introduced jQuery, a JavaScript library that makes web programming a whole lot easier. jQuery is the most popular of many libraries that allow us to interact with the document easily, while also providing us with a few tools that are missing from the base language.
  
==== Class for 2012-12-10: jQuery, cont'd ====

==== Class for 2013-05-13: CSS positioning ====
Floating is the secret sauce behind creating websites with multiple columns, navigation menus, and basically any block element that's aligned to the left or right. We learned about floats by taking a look at some examples, then took a [http://jeffreyatw.com/static/frontend/series2/class4/mockup.png mockup] and created a site from it.
+
In the last few classes, we focused on element measurements and floats. This time, we focused on positioning of elements: spacing them out from other elements using margins, and using absolute, relative, or fixed positioning to put the elements anywhere we want on the whole page.

Revision as of 16:47, 18 September 2013

Notes from previous Frontend Web Development classes.

Contents

Class for 2013-09-16: CSS3

We'd covered CSS3 before, but in the context of a mockup. We looked further into CSS3 with a demonstration of what the new technologies are, how to make the most of them, and how to make sites using them look good in less capable browsers.

Class for 2013-09-09: HTML5 elements

We took an entertaining (in my opinion) look through this page containing every currently valid HTML element. Many of them are considered "HTML5" elements, but that's just because they're relatively new.

Class for 2013-08-26: ClassName Swap, Language Review, RTFM, by Garrett Smith

Lesson: CSS ClassName Swap

By changing an element's className multiple styles can be changed at one time.

Using the descendant selector, and changing the className of an ancestor element, multiple elements can be updated simultaneously, with a modicum of highly efficient code.

For Styles, replace a loop that applies styles to descendants by adding a class token to the nearest common ancestor (example, explanation).

Calculating Selector's Specificity (CSS 2.1).

The classname swap example leverages the fact that class selectors (e.g. .foo) have higher specificity than element selectors (e.g. tr).

CSS Selector specificity is determined four numbers, a-b-c-d, in a number system with a large base.

count 1 if the declaration is from is a 'style' attribute rather than a rule with a selector, 0 otherwise (= a) (In HTML, values of an element's "style" attribute are style sheet rules. These rules have no selectors, so a=1, b=0, c=0, and d=0.) count the number of ID attributes in the selector (= b) count the number of other attributes and pseudo-classes in the selector (= c) count the number of element names and pseudo-elements in the selector (= d)
RTFM

Unschooling and autodidacticism; an Intro to RTFM, RTFFAQ, and SFTW.

Understanding defines the difference between the followers, who resort to mystical incantations or convoluted DOM libraries to do the work for them, and those who can implement project requirements, as specified, with clean code (Vimeo). And not downloading free scripts off dynamic drive or [ jQuery], copying, or programming by observation.

When misunderstandings or debates arise, and that happens fairly often, it is important how to find the answer using STFW and RTFM, and when that fails, how (and where (CIWAS, JSMentors, c.l.js, ciwah) to ask a smart question.

Specifications

Other versions of ECMAScript, including E4X and Compact, are out of scope for this class.

Class for 2013-08-12: More useful jQuery plugins

Our final jQuery-focused class touched on a number of other common plugins that are found in the wild. We took a closer look at Bootstrap and jQuery UI, and looked at plugins that make your page look super snazzy:

Class for 2013-08-05: Sign-up forms

We continued working on our site and added a sign-up form, with validation, inside the modal. We used the jQuery Validation plugin. Validation is a very common request from clients and it comes in handy to know all the tips and tricks of forms and validation, and what new HTML5 elements can provide.

Class for 2013-07-29: Modals and menus

We went back to the "professional" site we'd put together a number of weeks ago and added more functionality to it with some jQuery plugins. We first made a dialog box - or a "modal" - pop up when you click the sign up buttons. We did this by introducing jQuery UI to make common user controls easier to create. We also added some dropdown functionality to our menus using pure CSS, but explained that jQuery UI can help out with the subtle nuances of menus.

Class for 2013-07-22: AJAX

We talked about Asynchronous JavaScript and XML, a technology that allows us to talk to a server without leaving the page. jQuery makes this extremely easy. We added AJAX functionality to our app we've been building on. We used this PHP file to test it out.

Class for 2013-07-15: jQuery, cont'd

We continued learning about jQuery by focusing on the example we saw last week. We added functionality to it that made it seem more like the real thing.

Class for 2013-07-08: jQuery

We introduced jQuery, a JavaScript library that makes web programming a whole lot easier. jQuery is the most popular of many libraries that allow us to interact with the document easily, while also providing us with a few tools that are missing from the base language.

To learn what jQuery can do, we added some scripting to this sample web app.

Class for 2013-07-01: JavaScript, cont'd

We continued discussing JavaScript basics: arrays, objects, creating functions, and scopes.

Class for 2013-06-24: JavaScript

We talked about JavaScript: making web pages interactive through client-side code. We used the console, which is part of the browser's developer tools, to demonstrate the basics of the language. This and next week's class can be treated as a general introduction to programming.

Class for 2013-06-17: HTTP & SFTP

We talked about file transfer: HTTP, which is the method of getting and sending information in the web browser, and SFTP, which is a method of securely uploading files to a web host.

We set up free web hosting accounts at NearlyFreeSpeech.NET, and uploaded to them using the FileZilla client.

Class for 2013-06-03: Working from professional mockups, cont'd

We continued putting our professional-looking site together from where we left off. We focused on some fancy CSS3 techniques, and we saw how to make an interactive dropdown menu with no JavaScript.

We didn't exactly finish, but I went ahead and put on the finishing touches. The final product can be found here (but where we left off can be found in the lecture materials).

Class for 2013-05-20: Working from professional mockups

We took the knowledge we gained from looking at the CSS box model, floats, and positioning, and worked off of something given to us by a designer (me).

We worked off of this mockup and its annotated version to make a site that could pass as a professional design (but don't take my word for it). Image assets can be found here.

Class for 2013-05-13: CSS positioning

In the last few classes, we focused on element measurements and floats. This time, we focused on positioning of elements: spacing them out from other elements using margins, and using absolute, relative, or fixed positioning to put the elements anywhere we want on the whole page.

Class for 2013-05-06: CSS floats

Floating is the secret sauce behind creating websites with multiple columns, navigation menus, and basically any block element that's aligned to the left or right. We learned about floats by taking a look at some examples, then took a mockup and created a site from it.

Class for 2013-04-22: CSS selectors and the box model

CSS selectors are probably the most complex part of the CSS language, so we looked at them further in-depth. We also talked about the box model, the display concept that makes words and containers on the web look like they do.

Class for 2013-04-15: the basics

We covered the very basics:

  • Explaining "frontend" vs. "backend"
  • Discussing tools of the trade
  • Explaining the separation between structure, presentation, and behavior
  • Writing a basic HTML page
  • Styling the page with basic CSS
  • Explaining the role of frontend web development as a job and career
