placeholder property
The placeholder property helps you optimize user experience, CLS, and implement the LQIP technique.
TwicPics Components automatically adds a background placeholder to your images: their size are reserved in the page before the images are actually loaded.
The placeholder values can be: preview , meancolor , maincolor or none .
The browser is told to load a SVG version as a backgroung image first, then to replace it with the full version later on.
When set to preview (the default value), a blurry version of your image is used as a background image.
