  • Don't underline any text that's not a link
  • The color for unvisited links should be more vivid, bright, and saturated than the color for visited links, which should look "used" (dull and washed out).
  • The two colors should be variants or shades of the same color, so that they're clearly related.
  • ...1 more annotation...
  • Don't place links so close together that users with reduced motor skills will have difficulty selecting them.

  • many dyslexic users are sensitive to the brightness the high contrast colors cause
  • use an off-white color for your background, like a light gray or tan. You can also use a dark gray for your text instead of pure black to cut the glare even more
  • dyslexic users need more breaks between ideas than non-dyslexic users
  • ...4 more annotations...
  • Breaking up your text to one idea per paragraph makes reading a lot easier for both dyslexic and non-dyslexic users.
  • a sans-serif font would allow dyslexic users to see the shapes of letters clearer
  • you shouldn’t use italicized text because they make letters hard to read
  • avoid creating the river effect by using left aligned text, instead of justified text for your paragraphs

    Empathy is unrivalled as a skill a user interface designer should have. Walking in somebody else's shoes (or seeing through their eyes may be a better metaphor), can be a temporary replacement for having a user/tester at hand. Let's take a look at some disabilities that we so often forget.

  • To enable subtitles by default, you will need to use &cc_load_policy=1 parameter
  • 3. Linking to Videos with Captions If you want to share a link to the video for viewers to see captions by default, you need to add this code at the end of the URL string: &yt:cc=on

      If there aren't any existing URL parameters, instead of appending &yt:cc=on you may need to use /?yt:cc=on For example https://youtu.be/GUfCPMCMORM/?yt:cc=on

Don't Use The Placeholder Attribute - Smashing Magazine - 0 views

shared by Vernon Fowler on 27 Jun 18 - No Cached
  • To recap, the placeholder attribute: Can’t be automatically translated; Is oftentimes used in place of a label, locking out assistive technology; Can hide important information when content is entered; Can be too light-colored to be legible; Has limited styling options; May look like pre-filled information and be skipped over.
  • Move the placeholder content above the input, but below the label:
  • Development Here’s how to translate our designed example to code:
  • ...4 more annotations...
  • aria-describedby ensures that the p content will be described last, after the label’s content and the kind of input it is associated with.
  • By using aria-describedby to programmatically associate the input with the p element, we are creating a priority of information for screen readers that has parity with what a person browsing without a screen reader would experience.
  • The floating label effect, a close cousin to this phenomenon, oftentimes utilizes the placeholder attribute in place of a label, as well.
  • Content hidden by an on-screen keyboard. 3rd party keyboards with larger heights may have a greater risk of blocking important content.
  • Vernon Fowler on 27 Jun 18
     
    Not only argues for not using the placeholder attribute but also describes an inclusive input hint and how to code it.

  • styles each header element differently depending on the value of its itemprop attribute. Using itemprop, we’re able to ensure that the author, publication date, title, and subheading are prominently featured.
  • If you plan to put things into microdata, please note that Apple, being Apple, go their own way, and don’t use a schema.org vocabulary here. Le sigh. See my article Content needs a publication date! for more. Or view source on this page to see how I’m using microdata on this article.
  • Apple WatchOS also optimises display of items wrapped in <figure> elements
  • ...4 more annotations...
  • First, choose the appropriate type attribute and element tag for your form controls. WebKit supports a variety of form control types including passwords, numeric and telephone fields, date, time, and select menus. Choosing the most relevant type attribute allows WebKit to present the most appropriate interface to handle user input.
  • unlike iOS and macOS, input methods on watchOS require full-screen interaction. Label your form controls or specify aria label or placeholder attributes to provide additional context in the status bar when a full-screen input view is presented.
  • By choosing the right semantics now, a machine that I don’t know about yet can understand my content and display it in the best way for its users.
  • Semantic HTML will give usability benefits to many users, help to future-proof your work, potentially boost your search engine results, and help people with disabilities use your site.

  • there is no point in confusing your users with a link that goes nowhere and won’t open anything in another tab. Use a button and you won’t promise any functionality you don’t have.
  • links keep getting used for functionality that doesn’t go anywhere on the web or in the document

  • WAVE can analyze contrast ratios for all page elements at once.
  • Colorzilla is an excellent tool for extracting the color value from any page element.
  • You can append ?fcolor=0000ff&bcolor=ff0000 (where the fcolor value is the foreground color and the bcolor value is the background color) to the URL of this page to analyze colors directly from a link or URL (link example).
