In terms of defining the “open” in open web annotation, I tend to take a standards approach: the Hypothes.is tool is built upon, and our organization advocates for, open standards in web annotation.

The valueAsNumber IDL attribute represents the value of the element, interpreted as a number. On getting, if the valueAsNumber attribute does not apply, as defined for the input element's type attribute's current state, then return a Not-a-Number (NaN) value.

Screen readers for the blind can help them fill out a form more easily if the logical sections are broken into fieldsets with one legend for each one. A blind user can hear the legend text and decide, "oh, I can skip this section," just as a sighted user might do by reading it.

Fits the ideal behind HTML HTML stands for "HyperText Markup Language"; its purpose is to mark up, or label, your content. The more accurately you mark it up, the better. New elements are being introduced in HTML5 to more accurately label common web page parts, such as headers and footers.

Service workers are limited though. A site can opt to perform whatever substitutions it likes, but it can only do that for its own requests.

Eventually, you’ve got a realization of the way web development organizational structure works. Led by a project manager and supported by a project architect, it can not exist without frontend, backend, and full-stack programmers, DevOps, and Q/A engineers. Optionally, you may need UI/UX designer, business analyst, and SEO expert. Every team player separately and altogether, they make your wishes real. Now, when you know all members’ duties, it should be easier to address your questions and concerns to the right person.

try { const value = await localforage.getItem('somekey'); // This code runs once the value has been loaded // from the offline store. console.log(value); } catch (err) { // This code runs if there were any errors. console.log(err); }

The alternative was to have multiple scripts or stylesheet links on one page, which would trigger multiple HTTP requests. Multiple requests mean multiple connection handshakes for each link “hey, I want some data”, “okay, I have the data”, “alright I heard that you have the data, give it to me” (SYN, ACK, SYNACK). Even once the connection is created there is a feature of TCP called TCP slow start that will throttle the speed of the data being sent at the beginning of a request to a slower speed than the end of the request. All of this means transferring one large request is faster than transferring the same data split up into several smaller requests.

Universal Links allow you to register a series of domains that are allowed to interact with an installed application. If the application is not installed, the universal link is opened with Safari, allowing you to inform the user of the existence of an application or whatever is necessary.

Implicit intents do not name a specific component, but instead declare a general action to perform, which allows a component from another app to handle it. For example, if you want to show the user a location on a map, you can use an implicit intent to request that another capable app show a specified location on a map.

I prefer not to duplicate the name of the table in any of the columns (So I prefer option 1 above).

Although one thing you want to avoid is using frames in such a manner that the content of the site is in the frame and a menu is outside of the frame. Although this may seem convienient, all of your pages become unbookmarkable.

There is one situation where iframes are (almost) required: when the contents of the iframe is in a different domain, and you have to perform authentication or check cookies that are bound to that domain. It actually prevents security problems instead of creating them. For example, if you're writing a kind of plugin that can be used on any website, but the plugin has to authenticate on another domain, you could create a seamless iframe that runs and authenticates on the external domain.

Iframes can have similar issues as frames and inconsiderate use of XMLHttpRequest: They break the one-document-per-URL paradigm, which is essential for the proper functioning of the web (think bookmarks, deep-links, search engines, ...).

The most striking such issue is probably that of deep linking: It's true that iframes suffer from this to a lesser extent than frames, but if you allow your users to navigate between different pages in the iframe, it will be a problem.

never care and try to understand design standards

If you're creating an actual, informational web page, stick to frameless HTML, CSS and unobstrusive JavaScripts and keep in mind that the page should still be usable with scripting disabled.

I normally try to figure out if that's a good solution for the problem before resorting to iframes. Sometimes, however, an iframe just does the job better. It maintains its own browser history, helps you segregate CSS styles if that's an issue with the content you're loading in.

that's a point, but I would say the opposite, when entering credit card data I would rathre prefer to be entirely in the Verified By Visa (Paypal) webpage (with the url easily visible in the address bar) rather that entring my credit card data in an iframe of someone's website.

Then recently I was shopping at the John Lewis website, and they brought up the Verified By Visa page in an iframe - wonderful! I'm still looking at the John Lewis site, and all that's happening is I'm being asked for my Verified By Visa password - no problem. Although as a web developer I know that there's no technical difference between that and a plain old redirect-there-redirect-back, the user experience is so much better!

It’s kind of like putting a SIM card in a cell phone – the SIM card tells that phone, “Hey, you work with this particular phone number now.” Just like you can switch out a phone’s SIM card and make the phone work with a different phone number, your domain can be set to work with a different web hosting service.

As soon as you're displaying content from another domain, you're basically trusting that domain not to serve-up malware. There's nothing wrong with iframes per se. If you control the content of the iframe, they're perfectly safe.

IFRAME element may be a security risk if any page on your site contains an XSS vulnerability which can be exploited

Your browser window is basically just one big iframe.

First, the frame and frameset elements are not deprecated in HTML5, they're obsolete (i.e., they've been removed entirely).

many a tech manager has siezed on them as a solution to many problems. In fact, they create more.

if used for parameterized content, they've created an interface. And in a professional site, that interface requires an SLA and version management - which are almost always ignored in rush to get online.

And if your framed content has a need to be interactive, it will struggle to do so beyond the frame.

Usually, if you can do it without an iframe, that is a better option. I'm sure others here may have more information or more specific examples, it all comes down to the problem you are trying to solve.

think about them as a text/markup equivalent to the way a video or another media file would be embedded

The downside is that if you introduce multiple layers of scrolling (one for the browser, one for the iframe) your users will get frustrated. Like adzm said, you don't want to use an iframe for primary navigation

on the other hand, documents from different origins can still communicate using window.postMessage(), for example to implement collaborative iframe auto-resizing.

but I wouldn't use a frameset for anything but a manual since it no longer exists in html5. Example: Game maker manual

However I've seen iframes abused as well. It should never be used as an integral part of your site, but as a piece of content within a site.

Designers hated them. Yes, that was the deadliest punch. Everything looked square and straight. They hated it. They wanted arcs and image backgrounds and rounded borders. Now they have it in CSS3 - guess what, they're drawing squares. #whatever Programmers had trouble with them. It was inconvenient to follow the logic of frames, and you had to do some extra work. I mean, some. Today it's a lot harder to create AJAX solutions for the same problem, but no one complains. #whatever Websites could include one another. This was painful for some site owners because they worked hard on something and another fella used it as own content. Later, they invented same origin policy, but it was way after starting to hate frames. Content stealing is still an issue today, absolutely unrelated to whether we have frames or not. #whatever Back button worked differently. Yes, it was a bit annoying. But it was not the frame concept's fault, again: it was browsers who did this to us. Could have been solved easily, but nah, browsers kept going back one by one, not providing the site a way to implement its own "step back" method, and alas, this is still happening today. #whatever

6. Add Purgecss for unused CSS removal (optional) Add Purgecss to Sage. Once you’ve successfully added Purgecss, you will need to complete an addition step to make sure Purgecss can extract Tailwind’s classes properly. Luckily, Tailwind has a guide in their docs to add a custom Purgecss extractor.

Twitter threads gave illness a name and a face, grounding the dread in particular bodies and disparate — if often overlapping — experiences. They placed these experiences in history, creating an archive of disease, fear, rage, and hope that will persist even as these feelings — and some of these people — have passed.

I used it to create a full-bleed utility class: .full-bleed { width: 100vw; margin-left: calc(50% - 50vw); }

class Session extends Map { set(id, value) { if (typeof value === 'object') value = JSON.stringify(value); sessionStorage.setItem(id, value); } get(id) { const value = sessionStorage.getItem(id); try { return JSON.parse(value); } catch (e) { return value; } } }

I think that the webStorage is one of the most exciting improvement of the new web. But save only strings in the value key-map I think is a limitation.

The Web Storage API provides mechanisms by which browsers can store key/value pairs, in a much more intuitive fashion than using cookies.

Andrew Bosworth, one of Facebook’s longtime executives, has compared Facebook to sugar—in that it is “delicious” but best enjoyed in moderation. In a memo originally posted to Facebook’s internal network last year, he argued for a philosophy of personal responsibility. “My grandfather took such a stance towards bacon and I admired him for it,” Bosworth wrote. “And social media is likely much less fatal than bacon.”

Facebook’s stated mission—to make the world more open and connected—

Svelte components are a thin layer over the DOM and naturally expose the web platform. Coding in Svelte feels like I’m moving with the grain of the web.

Serving pages and assets as pre-generated files allows read-only hosting reducing attack vectors even further. Meanwhile dynamic tools and services can be provided by vendors with teams dedicated to securing their specific systems and providing high levels of service.

Because Jamstack projects don’t rely on server-side code, they can be distributed instead of living on a single server. Serving directly from a CDN unlocks speeds and performance that can’t be beat. The more of your app you can push to the edge, the better the user experience.

Because Jamstack markup is prebuilt, content changes won’t go live until you run another build.

Better PerformanceWhy wait for pages to build on the fly when you can generate them at deploy time? When it comes to minimizing the time to first byte, nothing beats pre-built files served over a CDN.

I'm not familiar with Svelte. But the UI itself is handled in a custom canvas on mobile (and probably Desktop?) Though, on the web, it is HTML and CSS.

Unfortunately it is not just the semantic that is broken. There are lot of things.For example if you look at some of the examples (https://flutter.github.io/samples/#/) - you can see that indeed there are some div and p tags but it is not entirely normal DOM elements. For example you can't even select text anywhere on the screen. And there are more and more little things like that.Just to be clear - Flutter for web is great, I'm happy it exists, but it is not comparable to React/Vue or Svelte.IMO Flutter for web is good to post live examples of Flutter code or maybe some last-minute-boss-request to make a web version of existing app, but for not for full-blown web app. :)

When writing copy for buttons, make sure that you keep consistency.

Make sure the label colour stands out against the button fill. You can check using http://accessible-colors.com/. Always make sure that your colours meet the AAA requirements.

Text links are a very simple button type.

Some text links may have an icon with them.

This one gets the SEO, so I hope you're successful @raythurnevoid.

Capacitor's origins lie in Ionic's mission to provide a holistic framework for developing hybrid apps—apps that run on mobile devices, on desktops, and in the browser. It does not only replace Apache Cordova as a “bridge” to native platform access in new Ionic projects but also “provides a consistent, web-focused set of APIs”.

Capacitor is a framework that provides developers a coherent API set to access various features on different platforms. By doing so, it also simplifies using those features. Especially for web APIs that are hard to use or require multiple steps to set them up, Capacitor provides an easy-to-use interface.

these platforms aim to provide experiences “that people want to use that works as much as possible as they expect, but which is backed up by better values and technology.”

The 2000's utopian dream for computer programs was the ‘semantic web’- which for me is still a little raw to talk about.

The websites of today are primarily built with efficiency and usefulness in mind, but in turn, they often lack the creativity, playfulness, and dedication that make a site stand out and a joy to interact with.

Gabriela Grosseck* West University of Timisoara, 4 Bd. C. Coposu, office 029, 300223 Timisoara, Romania Received October 8, 2008; revised December 16, 2008; accepted January 4, 2009 Abstract Web 2.0 has been, during the last years, one of the most fashionable words for a whole range of evolutions regarding the Internet. Although it was identified by the current analysts as the key technology for the next decade, the actors from the educational field do not really know what Web 2.0 means. Since the author started to explore and use Web 2.0 technologies in her own development/improvement, she has been intrigued by their potential and, especially, by the possibility of integrating them in education and in particular in the teaching activity. The purpose of this paper is both to promote scholarly inquiry about the need of a new type a pedagogy (Web 2.0 based) and the development / adoption of best practice in teaching and learning with web 2.0 in higher education (HE). The article main objectives are: • to introduce theoretical aspects of using Web 2.0 technologies in higher education • to present models of integrating Web 2.0 technologies in teaching, learning and assessment • to identify the potential benefits of these technologies as well as to highlight some of the problematic issues / barriers encountered, surrounding the pedagogical use of Web 2.0 in higher education • to propose an agenda for future research, and to develop pedagogy 2.0 scenarios for HE sector. © 2009 Elsevier Ltd.

found. The PST concern was most intense in the self-concern stage and then fluctuated from task-concern to impact-concern within a small range. Findings of the study provide valuable insights for personalising teacher education as to how levels of concern, self-efficacy for teaching, teacher knowledge and demographics influence the change process required for Web 2.0 integration in instruction.
