This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being served over HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more about HTTPS.
Isuprssa.com Mobile Accessibility: 90/100
Quick overview:
Contrast
These are opportunities to improve the legibility of your content.
Background and foreground colors do not have a sufficient contrast ratio.
Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.
Names and labels
These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Image elements have `[alt]` attributes that are redundant text.
Informative elements should aim for short, descriptive alternative text. Alternative text that is exactly the same as the text adjacent to the link or image is potentially confusing for screen reader users, because the text will be read twice. Learn more about the `alt` attribute.
Tables do not use `<caption>` instead of cells with the `[colspan]` attribute to indicate a caption.
Screen readers have features to make navigating tables easier. Ensuring that tables use the actual caption element instead of cells with the `colspan]` attribute may improve the experience for screen reader users. [Learn more about captions.
Best practices
These items highlight common accessibility best practices.
Touch targets do not have sufficient size or spacing.
