List of things that broke with the Opera 15 release due to the switch to Blink/Chromium (Web features, not UI-specific stuff)

This is how BBC News currently implements it's Image Enhancer for responsive images. Note: this is a completely rebuilt version of the code so the BBC's original source code doesn't actually look anything like the below example.

The BBC has a server-side image service which provides developers with multiple sized versions of any image they request. It works in a similar fashion to http://placehold.it/ but it also handles the image ratios returned (where as placehold.it doesn't).

The original BBC News process (and my re-working of the script) follows roughly these steps...

  • Create new instance of ImageEnhancer
  • Change any divs within the page (which have a class of delayed-image-load) into a transparent GIF using a Base64 encoded string.
    • We set the width & height HTML attributes of the image to the required size
    • We know what size the image needs to be because each div has custom data-attr set server-side to the size of the image
    • We then set a class of image-replace onto each newly created transparent image
  • We use a 250ms setTimeout to unblock the UI thread and which calls a function resizeImages which enhances the image-replace images so their source is now set to a URL whe

Fix SVGs not scaling in IE9, IE10, and IE11

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.
