Logo Slider – Infinite Carousel & Marquee Block for WordPress

Adjustable Logo Height – Set custom height from 30px to 150px

Mobile Logo Height – Optional separate logo height for phones, or fully automatic scaling

Balanced Logo Sizes – Optionally equalize the visual weight of wide and compact logos automatically

Text Marquee Block – Second block: infinitely scrolling text ticker for reviews, badges or announcements

Pause Button – Optional pause/play control for better accessibility (WCAG 2.2.2)

Alt Texts from the Media Library – Missing alt texts are filled in from the attachment while the page renders, so alt texts maintained in the media library reach the front end without touching the block

Screen Reader Friendly Loop – The repeated logo sets are hidden from assistive technology, so a client name is announced once instead of once per copy

Lazy Loading – Logos load lazily by default and are only measured once the carousel comes into view, which keeps them off the critical path

Grayscale Mode – Logos run desaturated for a calm, uniform look

Original Colors on Hover – Optional: logos return to their original colors on hover, combinable with every color mode

Wide & Full Alignment – Native Gutenberg wide/full-width support

Responsive Design – Perfect display on all devices and screen sizes

SEO-Friendly – Clean, semantic HTML markup

Lightweight – Optimized for performance with minimal impact

No jQuery Required – Pure JavaScript for better performance
