you can see an example of this in our responsive.html example on github (see also the source code): <img srcset="elva-fairy-480w.jpg 480w, elva-fairy-800w.jpg 800w" sizes="(max-width: 600px) 480px, 800px" src="elva-fairy-800w.jpg" alt="elva dressed as a fairy"> the srcset and sizes attributes look complicated, but they're not too hard to understand if you format them as shown above, with a different part of the attribute value on each line.
...for each one, we write: an image filename (elva-fairy-480w.jpg) a space the image's intrinsic width in pixels (480w) — note that this uses the w unit, not px as you might expect.
... a space the width of the slot the image will fill when the media condition is true (480px) note: for the slot width, you may provide an absolute length (px, em) or a length relative to the viewport (vw), but not percentages.

...so it will print the value of loworhi to the console as soon as we have tried to set it in line 48.
... sure enough, loworhi's value is null at this point, so there is definitely a problem with line 48.

it looks like this: if (window.matchmedia("(max-width: 480px)").matches) { // run javascript in here.
... } as an example, our snapshot demo makes use of it to selectively apply the brick javascript library and use it to handle the ui layout, but only for the small screen layout (480px wide or less).
... we first use the media attribute to only apply the brick css to the page if the page width is 480px or less: <link href="dist/brick.css" type="text/css" rel="stylesheet" media="all and (max-width: 480px)"> we then use matchmedia() in the javascript several times, to only run brick navigation functions if we are on the small screen layout (in wider screen layouts, everything can be seen at once, so we don't need to navigate between different views).
... if (window.matchmedia("(max-width: 480px)").matches) { deck.shuffleto(1); } using modernizr to implement feature detection it is possible to implement your own feature detection tests using techniques like the ones detailed above.

the analyser node will then capture audio data using a fast fourier transform (fft) in a certain frequency domain, depending on what you specify as the analysernode.fftsize property value (if no value is specified, the default is 2048.) note: you can also specify a minimum and maximum power value for the fft data scaling range, using analysernode.mindecibels and analysernode.maxdecibels, and different data averaging constants using analysernode.smoothingtimeconstant.
... so for example, say we are dealing with an fft size of 2048.
... analyser.fftsize = 2048; var bufferlength = analyser.frequencybincount; var dataarray = new uint8array(bufferlength); to actually retrieve the data and copy it into our array, we then call the data collection method we want, with the array passed as it's argument.
... creating a waveform/oscilloscope to create the oscilloscope visualisation (hat tip to soledad penadés for the original code in voice-change-o-matic), we first follow the standard pattern described in the previous section to set up the buffer: analyser.fftsize = 2048; var bufferlength = analyser.frequencybincount; var dataarray = new uint8array(bufferlength); next, we clear the canvas of what had been drawn on it before to get ready for the new visualization display: canvasctx.clearrect(0, 0, width, height); we now define the draw() function: function draw() { in here, we use requestanimationframe() to keep looping the drawing function once it has been s...

ETag - HTTP
Web › HTTP › Headers › ETag
examples etag: "33a64df551425fcc55e4d42a148795d9f25f89d4" etag: w/"0815" avoiding mid-air collisions with the help of the etag and the if-match headers, you can detect mid-air edit collisions.
... for example, when editing mdn, the current wiki content is hashed and put into an etag in the response: etag: "33a64df551425fcc55e4d42a148795d9f25f89d4" when saving changes to a wiki page (posting data), the post request will contain the if-match header containing the etag values to check freshness against.
... if-match: "33a64df551425fcc55e4d42a148795d9f25f89d4" if the hashes don't match, it means that the document has been edited in-between and a 412 precondition failed error is thrown.
...if a user visits a given url again (that has an etag set), and it is stale (too old to be considered usable), the client will send the value of its etag along in an if-none-match header field: if-none-match: "33a64df551425fcc55e4d42a148795d9f25f89d4" the server compares the client's etag (sent with if-none-match) with the etag for its current version of the resource, and if both values match (that is, the resource has not changed), the server sends back a 304 not modified status, without a body, which tells the client that the cached version of the response is still good to use (fresh).

Legacy layout methods - Learn web development
Learn › CSS › CSS layout › Legacy Layout Methods
add the following to the bottom of your css: div:nth-of-type(1) { width: 48%; } div:nth-of-type(2) { width: 48%; } here we've set both to be 48% of their parent's width — this totals 96%, leaving us 4% free to act as a gutter between the two columns, giving the content some space to breathe.
... now we just need to float the columns, like so: div:nth-of-type(1) { width: 48%; float: left; } div:nth-of-type(2) { width: 48%; float: right; } putting this all together should give us a result like so: simple two-column layout <h1>2 column layout example</h1> <div> <h2>first column</h2> <p>lorem ipsum dolor sit amet, consectetur adipiscing elit.
...cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.</p> </div> body { width: 90%; max-width: 900px; margin: 0 auto; } div:nth-of-type(1) { width: 48%; float: left; } div:nth-of-type(2) { width: 48%; float: right; } you'll notice here that we are using percentages for all the widths — this is quite a good strategy, as it creates a liquid layout, one that adjusts to different screen sizes and keeps the same proportions for the column widths at smaller screen sizes.

mathml font selection with css you can get these fonts from the mathml-fonts add-on ; the xpi is just a zip archive that you can fetch and extract for example with the following command: wget https://addons.mozilla.org/firefox/downloads/latest/367848/addon-367848-latest.xpi -o mathml-fonts.zip; \ unzip mathml-fonts.zip -d mathml-fonts then copy the mathml-fonts/resource/ directory somewhere on your web site and ensure that the woff files are served with the correct mime type.
Using the viewport meta tag to control layout on mobile browsers
Mozilla › Mobile › Viewport meta tag
enter viewport meta tag however, this mechanism is not so good for pages that are optimized for narrow screens using media queries — if the virtual viewport is 980px for example, media queries that kick in at 640px or 480px or less will never be used, limiting the effectiveness of such responsive design techniques.
