Using This Website (some useful tips)

iPad Failure - Frames - No Frames?
Links - Ethics - Javascript - Printing


One Page or Two Pages:  Some pages now have two links in the upper-right corner, to "open only this page" or to open two pages and either "put page into left frame" or "put page into right frame".   Usually the first link, opening one page, is better for a small-screen cell phone or small tablet, or a large tablet that's in narrow portrait-mode.  I think the second link, opening two pages, is better for a large-screen computer monitor, or tablet in wide landscape-mode.  But you can decide whether you want one page or two, and control it.

In this page, you'll find more about iframes and about links (plus ethics, grammar, printing)


CONTROL of the two iframes

Why does this website use iframes?

In the top-right corner of each page is a link (labeled "put page into left frame" or "put page into right frame") that makes a page open “where it should be” in either the left iframe or right iframe.

Many pages (especially the “main pages”) now have links that let you "open only this page" if you want to view it in the full-width of your device;  this is especially useful for a small-screen smartphone.

Use your Back-Button, once or twice, to return the iframes (on left side & right side) to what they were.

terms:  In this website, "frames" and "iframes" both mean iframes.


No Frames?In this website you always should see a frame-set with two pages, in the left-side iframe and right-side iframe.  The only exception is that when you click an italicized link, the frame-set may get hidden beneath the new window that opens, as explained above.  If (for some unusual reason) one page occupies the full width of your browser window, you can get the frame-set by clicking either the top-of-page link for "into left frame" or "into right frame", or "Home + Sitemap" or this link.


iPad failure success

update:  iframes now work properly with iPad & iPhone, although many previous versions of iOS (for iPads & iPhones) did fail with iframes;  recently I discovered that iOS 13 (and probably earlier) shows iFrames properly.

The Problem:  Unfortunately, [in the past] iPads (using iOS) could not display iframes properly.  Apple has known about this failure since early 2011, but doesn't seem to care.

A Partial Solution:  You can explore this website using any other device — on a tablet (or phone) using Android OS, or a computer — because its iframes work properly with Android, and with Windows & Mac using all major browsers: Firefox, Chrome, Explorer, Safari,...    (and with any device you can "open only this page" as explained above)

Another Partial Solution:  If you do use an iPad, you can touch-and-hold a link and select "Open Link in New Tab" which lets you see the page in a full-width window, although you won't see the visual benefits of the website's two-frame design.



The color-highlighting that surrounds a link shows that the link goes to another part of the same page or to a Page for a Main Topic or, more often, to the Page with Summaries of the Main-Topic Pages.

An italicized link opens the new page in a separate new full-width window, so the two current frames (the ones you see now) will remain open in this two-frame window.  Usually this occurs for a "new page" that isn't part of this website, so you'll know that it isn't part of this website.



Here is how you can link to a pair of pages inside this website (and put them into the left-side iframe & right-side iframe) from an external web-page:

• for the sitemap-and-homepage, use https://educationforproblemsolving.net/design-thinking/ (the page - index.htm - isn't required)

• for any other page, the 5 formats below will put "dp-mo.htm" into the right-frame or (where it belongs) left-frame, or load two pages (left & right), or open a page at a specific location within it, or open the Home-Page and a Page-with-Summaries.

right, https://educationforproblemsolving.net/design-thinking/index.htm?right=dp-mo.htm

left, https://educationforproblemsolving.net/design-thinking/index.htm?left=dp-mo.htm%23empathy.htm

two, https://educationforproblemsolving.net/design-thinking/index.htm?left=dp-mo.htm%23emrel&right=ws.htm%23dpmo1ab

one page, https://educationforproblemsolving.net/design-thinking/dp-mo.htm#emwhat

Home & Summaries, https://educationforproblemsolving.net/design-thinking/index.htm

comments:   Each page is designed to be in either the left-side or right-side iframe.  For example, "home.htm" (the home-page) usually should be on the left side, because most of its links open on the right side.  But "ws.htm" (the main content-page) should be on the right side, because most of its links open on the left side.   /   An anchor — which takes you to a specific location within the page — is changed from the usual URL-format (...dp-mo.htm#empathy) to (...dp-mo.htm%23empathy) by replacing # with %23 for the anchor named "empathy".


ETHICS — Frames and Links

For ethical reasons, so you'll know what is and isn't my work, a page made by someone else will never appear in a left-side or right-side frame.   If a page in a full-width window (after you click an italicized link) has a URL beginning with "educationforproblemsolving.net" or "asa3.org" it's mine.  If not, someone else made the page.


ILLOGICAL “RULES” for Grammar & Spelling

My disdain for some “rules” that are illogical — which I feel free to break, and do — is described in Details about the Website.  Examples include not splitting infinitives, which often produces a sentence with awkwardly foolish ordering of words (so instead I have chosen to write non-awkward sentences), illogically inconsistent “correct" spellings like those for remembering (correct according to customary rules) and transferring (correct according to customary rules) so instead of following the illogical custom I have chosen rationality by spelling both "...ering", and more.     {update about split infinitives:  to boldly go & current guidelines have become more rational by acknowledging that "not only is the split infinitive correct, but it should be furthered rather than censured, for it makes for clearer expression" because it "eliminates all possibility of ambiguity" instead of causing "potential for confusion."}



Black & White:  To save colored ink and paper, I've made a separate "style sheet" [for some pages] so that, compared with what you see on-screen, pages print with these changes:  the bottom part of page (Back-Button, "If you have questions,...") doesn't print;  background colors (for page & links)* don't print;  most text-colors (for purple titles, blue links, green links) prints black, but other colors & diagrams print in color, so if you don't want any color, select "black & white" printing in your print setup;  print-font is "serif" (Times,...) because most people prefer this for reading, but want "non-serif" (Arial,...) for on-screen viewing.

Browser Behaviors:  On a Mac, Safari and Firefox behave well, Opera doesn't.  Later, I'll check Chrome-for-Mac, and Windows browsers.  Here are some details:

* For link-backgrounds, like the gold for Main-Topic Pages) you can over-ride my style sheet and make these print by selecting "print background" which, by default, is off (ok) for Safari & Firefox, but is on (wastes ink) for Opera;  see details below.

Mac-Safari:  where your mouse is, that frame gets printed, very simple;  click the third menu ("Copies & Pages") and then "Safari" where I suggest un-clicking "background" and maybe (since you may like these) headers/footers.

Mac-Firefox:  you must right-click (or option-click) to get a menu for "This Frame" and printing/etc;  click third menu ("Copies & Pages") and "Firefox" where I suggest turning "background" off, and you have many choices for headers & footers.

Mac-Opera:  this doesn't behave well for printing;  you must right-click on a frame & open it in a new window (or tab), then print;  there is no third menu link for "Opera" (as with Safari & Firefox) and the link-backgrounds print by default, and I can't find a way to stop it.   :<(

Mac-Chrome:  I'll check this later.

Windows-browsers:  later.


There were forum-reports about the failure of iPads (with iFrames) in 2011 & 2012 ( 1 - 2 - 3 ) and this difficulty continues to the present in late 2014.

* In a May 2011 blog-post Stacey explains that "Steve [Jobs] has decided in his infinite wisdom that we don't need to scroll iframes on his iPad.  At one point in time, he deemed it acceptable to allow iframes to scroll with two fingers, but apparently we are no longer [beginning with Apple's iOS 4.2.1] deserving of that luxury."  Since that time 3 years have passed, and the problem has not been solved in iOS 5, 6, or 7.    :<(


JAVASCRIPT - [i think these "red-highlighted links" are no longer used in the website]

Some features of the website — including links that change both frames with one click, or that take you directly to a location near the bottom of a page, or seeing red-highlighted links to show “where you are” (as explained in the homepage), and more — require JavaScript, so I recommend “enabling JavaScript” in your browser's Preferences, at least for this website.  But many other websites also use JavaScript.   (Java is different, and is not used in this website.
