Website Checking Tools¶

Responsiveness/mobile¶

• Firefox Responsive Design Mode (CTRL + SHIFT + M shortcut on linux)
• Resize the window to really small (mobile, or xs- in bootstrap, then increase a little to about 400-800 px when the medium viewport must trigger, or md I think in bootstrap)

Accessibility¶

• WAVE - https://wave.webaim.org/
• Firefox - Right click anywhere on the screen and "Inspect Accessibility Properties"
• Accessi - https://www.accessi.org/
• pa11y.org - https://pa11y.org/
• For contrast, my favorite is squinting my eyes… similar to how you can do to simplify colors in a painting… I find that when the text color fades and almost disappears, that's normally because of bad contrast, and users with disabilities/diseases that cause blurred vision probably won't be comfortable reading it (I did that for Arvados.org and noticed some text that was hard to read, before testing with WAVE & accessi :joy: I just try never let anyone see me doing it) - https://www.sightsize.com/the-value-of-squinting/
• ORCA Linux screen reader - I find that these automated reports are useful for auditing, but for really confirm if a site is accessible, the best is always to ask a person with a disability to test it, or use a screen reader. Windows has a screen reader that's a lot better than ORCA.

Performance¶

• Chrome Lighthouse - https://developer.chrome.com/blog/lighthouse-load-performance/

Link Check

• W3C Link Checker - https://validator.w3.org/checklink

Typos & Grammar¶

• WebStorm (it has a "Inspect" feature that uses a dictionary for typos, and a mix of custom language-rules & LanguageTools for Grammar). Not perfect, and I only run it when I have the code (I didn't use it for Arvados.org)

SEO¶

• These two pages recommended by google, for schema.org tags - https://developers.google.com/search/docs/advanced/structured-data (e.g. https://validator.schema.org/#url=arvados.org)

JS/CSS¶

• Firefox console, checking for warnings/errors.
