Joel at Cloud Native Wales meetup in Cardiff

👋 Welcome to the personal website of Joel Murphy. Here is a message from the author:

You’ve probably stumbled across this website because I’ve directed you here to learn from my tutorials, or to explore my travel experiences. Otherwise, there’s a chance you’ve been stalking my social media profiles and ended up clicking through to here? (hey, it’s okay - we’re all human and get curious sometimes! 😂) Anyhow, a warm welcome to you, regardless of how you ended up here! 😄

I’ve created this website as a central repository of information to document topics, events, and developments I find interesting in my personal & work life. You’ll find that the majority of the content posted here is about technology; this is because it’s the industry I work in and one of my favourite hobbies outside of work. I also post about my travels, conduct product reviews, and share money saving tips , which you non tech savvy visitors may be interested in reading about 📖.

You may have already noticed that I’ve used an absurd amount of emoji’s throughout this website. There’s no real reason why I’ve done this but I believe they add a nice personal touch to the content I write. Let’s be honest, who doesn’t love emoji’s? 😄 👌 💯

If you’re here to learn about technology related topics, you may be interested in my Tutorials, my Talks & Presentations, and my Blog Posts. I try to update these when I have free time (which isn’t very often sadly) 😔.

All of the content published to this website will be available in English. If the content I produce gains some popularity, I’d be more than happy to give permission for it to be translated into other languages. However, please notify me of any planned publications you hope to make ahead of time, as it would be appreciated to get accredited in the form of a link back to the original source 🔗.

That’s all for now. I hope you have a fantastic day 🌞 or night 🌝 - depending on which part of the world you’re from. 🌎 If you have any questions or concerns about the content on this website, or just want to chat, please feel free to reach out to me by clicking on the contact button located in the side bar of this website.

Cheers! 🍻🍻🍻

WCAG 2.1 accessibility training

03 Oct 2019
wcag accessibility training
Dac training – Digital accessibility centre WCAG 2.1 Best design, techniques, code samples. Accessibility is ensuring that all web based platforms and applications are accessible to ALL regardless of ability or age. Equality act 2010 – avoid legal action Positive PR in healthcare WCAG 2.1 POUR Principles Perceivable Operable Understandable Robust 13 guidelines 78 success criteria A – High priority AA – Medium priority AAA – Low priority 4 basic user groups: Physical (disabled physically) Cognitive (asperges, autism) Hearing (deaf from birth, partial hearing loss) Vision (low vision or blindness) Types of assistive technologies Desktop Voiceover (Mac) Jaws (Windows) NVDA (freeware) Switch control / keyboard only Speeach to text (Dragon Naturally speaking) Zoom / magnification Mobile Text to speech for Android (Talkback) Speech To Text for android (s-voice) Switch control for android Text to speech for ios (voiceover) Speech to text for ios (siri) Etc. Low vision Ziad (the speaker) only has 5% vision in his right eye. “Developers haven’t made any difference – they’ve made THE DIFFERENCE” Ziad has regained independence thanks to assistive technology. People’s lives are improved from this sort of work. Text may not be large enough to read so would need to resize to zoom into content Contract between text and the background may not be sufficient (W3C ratio 4.5.:1) Do not cause content to update elsewhere on screen after selecting an item Do not use ‘maximum scale 1’ as this completely disables zoom on mobile Ensure content does not update on screen after making a selection Carousels tend to cause problems for screen readers as they constantly read out text. If you have to use a carousel on a page then be sure to add a pause button to make it more accessible Popups and modals steal focus and are bad for screen readers UX design best practise – colour contrast. Colour contrast analyser is a good free tool for this Colour contrast to meet AA standard is 7:1 Do not use colour as the only indicator for a currently selected item on page (use aria metadata instead) Physical Keyboard controls is controlled by the tab key Spacebar or enter is used to active elements and links Don’t use buttons as links Dragon voice activation has a series of commands for interacting with webpage elements. E.g. ‘Click link’, ‘Click box’ Focus highlighting on background should have a good contrast. E.g. light blue on blue is useless Captchas are not good at all for accessibility. Use a fallback. Cognitive Reading age may be lower Busy page layout can be confusing (KISS) Dyslexia needs to be considered (font-style, text alignment) May easily distracted by animation Stick to left hand alignment Don’t use acronyms and abbreviations Tooltip popups on abbreviations Use images and text. Just images are bad Avoid flickering blinking and moving images and images of text If images flicker at a rate of more than 3 flashes per second, don’t use them Hearing Close Captions (CC) on videos Open captions are available to everybody as they’re always there Closed captions can be toggled as an optional feature This is the difference between open and closed captions VTML or web VTT file formats for videos. This can be specified in HTML video tags “Flesch Kincaid” language test Blind users Ensure users are notified before opening a new layer or pop up Ensure focus is placed on the new layer or pop up and trapped within the pop up when it appears. All images should have a valid alt attribute Give information about the image in relevance to the content on the page ‘Aria-hidden=”true”’ won’t be shown by assistive technology Class=”sr-only”  only screenreaders can see the specific element Open in new windows – show an icon so screenreaders are made aware that a link opens in a new window Pagination – go to first page is read out as two left chevrons Download buttons to files – Show filetype to user and download size Aria-label overrides text on an element which is really handy for creating appropriate texts for screenreaders Skiplinks should be used to skip to main content to avoid the user having to scoll down the page Page title – ({name of current page} – {name of website}) Tables – use a <caption> element to describe a table in the same way you would use a heading. A caption helps users find, navigate, and understand tables Use the ‘scope’ attribute to help distinguish between rows and columns. Headings should be hierarchical. Css should be used to style headings, not actual headings. Headings should never be empty Fieldsets should be used with grouped elements such as radio buttons and checkboxes. Use “aria-invalid” attribute for adding errors to a form Hint text is useful in forms as it can be used to provide a real example Give users enough time to complete a particular action on a webpage Notify a user if a session is about to timeout (adhere to security) Hint: Mobile number inputs – ensure it’s possible to input a space or specify it’s not possible to use them. Use lang=”cy” for welsh content on an individual element basis ‘View more link’ <- be more descriptive with these. E.g. ‘View more vanancies at {CompanyName}” ‘Axe’ is a free extension for chrome that can be downloaded to inspect and validate aria labels. Provide a page on the website giving accessibility instructions Accessibility ratings are done on a page-by-page basis HTML5 and aria <header> for headers <nav> for navigations <main> for main content <section> or <article> for semantics <aside> complementary information <footer> the footer Aria-role https://www.sitepoint.com/how-to-use-aria-effectively-with-html5/ aria-current for navigation (breadcrumb trails, step processes, etc) aria-labelledby can group together content by different ids aria-describedby is useful for hint texts. They are very similar to aria-labels but are read out differently by screenreaders aria-alert & aria-live speaks things out straight. Aria-tab Aria-expanded ‘Sortsite’ is a spidering tool that runs fully automated accessibility checks Along with automated testing, UAT is always helpful for testing UX and accessibility.

My week ahead (23/09/2019 to 27/09/2019): This week I’ll be travelling to London to attend a tech conference called Cloud Native London 2019. Cloud Native London is a 3 day event which was established to discuss all things Cloud related. Cloud Native London is an event I’ve been looking forward to attending for the the past 5 months, since discovering a meetup event called “Cloud Native Wales” in my hometown (Cardiff if you didn’t know already). In this blog post I want to discuss my plans for the week and what I hope to get out of attending the event.
