Opera 62 – Tools Cool intended for School!

Hello there! It’ s been six-odd weeks, and the march of improvement continues to, uh… march… progressingly. This means we have a brand new Firefox to share, by having an abundance of bug fixes, efficiency improvements, and (in particular) sugary developer tool treats! So stick in your napkin and enjoy this sampling menu of some of what’ t new in Firefox 62.

Shape Up Your Floats

CSS Shapes lets the floated element sculpt the stream of content around it past the classic rectangular bounding package we’ ve been constrained in order to. For instance, in the above screenshot plus linked demo, the text is wrap to the shape of the grapes compared to the image’ s border. You will find properties for basic shapes entirely up to complex polygons. There are of course great docs on all of this, but Opera 62 also includes new pedaling to both inspect and aesthetically manipulate CSS Shapes values.

You can learn more in Josh Marinacci’ ersus post on the new CSS Forms tooling from recently.

Variable Fonts Are usually Here!

No punny title, I’ mirielle just excited! OpenType Font Variants allow a single font file in order to contain multiple instances of the same typeface, encoding the differences between instances. Not only is it in one file, font creators may expose any number of variation axes that provide developers fine-grained control on how the font is rendered. These can become standard variations like font bodyweight (font weight 536 looks correct? no problem! ) or things that had been never previously available via CSS (x-height! serif-size! ). In addition to the candy-store possibilities for typography nerds, having the ability to serve a single file with several variants is a major page bodyweight savings. Lalu Callahan goes further on the grooviness to be found and how Opera makes it easy to tweak these brand new custom values.

Devtools Commands

The Creator Toolbar was an alternate command repl input in the Opera Developer tools, apart from the Web System. I say “ was” due to the fact as of Firefox 62, it has been eliminated. It was always a bit hard to find instead of as well-advertised as it could be, yet did encapsulate some powerful instructions. Most of these commands have been progressively moved elsewhere in the devtools, and this is definitely wrapped up in Firefox sixty two, so we’ ve removed the particular toolbar altogether.

Among the last commands to be migrated is certainly screenshot , that is a power-user version of the “ have a screenshot” button available in the devtools UI. The screenshot command is now obtainable as : screenshot in the Web Console. For instance , have you ever needed a high-res screenshot of a page for print? You are able to specify a higher pixel density for the screenshot via the command:

: screenshot --dpr 4

There are a bunch of other available choices as well, such as specifying output filenames, capture delays, and selector-cropped screenshots. Eric Meyer wrote a great primer on the power of : screenshot on his weblog, and it will change your page capture online game!

🌠 Did You Know: In addition to : screenshot , there are a bunch of other useful commands and magic variables obtainable from within the Web Console? You can learn information on MDN Web Docs .

Mo’ Pixels, Mo’ Sections

Do you have a 4k monitor? Do your browser home windows bathe in a wash of sufficient screen real-estate? Let your devtools stretch their legs with a new 3-column mode in the Page Inspector. Now you can pop the CSS Rules see into its own column, to allow you to view style information and the outstanding Grid tooling or Animations section side-by-side.

The Three-Column View toggle are available in the top-left of the Inspector part panel.

Streamlining MediaStream

If you’ ve individuals WebRTC’ s getUserMedia API , you may be familiar with a bit of branching logic when attaching a MediaStream object to a < video> or < audio> tag:

 navigator. mediaDevices. getUserMedia(  audio: true, video: true  )
. then(function(stream) 
  if ("srcObject" in video) 
    videoEl.srcObject = stream;
    videoEl.src = URL.createObjectURL(stream);

It’ s true that will earlier support for WebRTC necessary the use of the LINK API, but it was non-standard and is no longer necessary. Opera 62 removes support for moving a MediaStream to createObjectURL , so be sure you’ re using a proper capability verify as above.

Precisely why stop here?

I’ ve shown you a glimpse associated with what’ s new and thrilling in Firefox 62, but there’ s more to learn and appreciate! Be sure to check out the product release notes designed for user-facing features as well as a more full list of developer facing changes upon MDN .

Happy building!
