// UPDATE: In 2023, you should probably stop using this! The narrow version of Safari that

/**
 * Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will
 * load <script nomodule> anyway. This snippet solve this problem, but only for script
 * tags that load external code, e.g.: <script nomodule src="nomodule.js"></script>
 *
 * Again: this will **not** prevent inline script, e.g.:

The command line, in short…

wget -k -K -E -r -l 10 -p -N -F --restrict-file-names=windows -nH http://website.com/

…and the options explained

• -k : convert links to relative
• -K : keep an original versions of files without the conversions made by wget
• -E : rename html files to .html (if they don’t already have an htm(l) extension)
• -r : recursive… of course we want to make a recursive copy
• -l 10 : the maximum level of recursion. if you have a really big website you may need to put a higher number, but 10 levels should be enough.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Fix SVG in <img> tags not scaling in IE9, IE10, IE11

IE9, IE10, and IE11 don't properly scale SVG files added with img tags when viewBox, width and height attributes are specified. View this codepen on the different browsers.

Image heights will not scale when the images are inside containers narrower than image widths. This can be resolved in 2 ways.

Use sed in bash to remove width and height attributes in SVG files

As per this answer on Stackoverflow, the issue can be resolved by removing just the width and height attributes.

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
