Placeholder Image Generator是什么？
Placeholder images are stand-ins for real content during design and development. They let you test layouts, performance, and responsive behavior without shipping a final image. This generator builds them as inline SVG so there is no network call — the image is just text in your markup.
Pick a width, height, background color, foreground color, and optional text. Grab the result as a data URL (drop into <img src=…>) or as raw SVG (drop into your markup directly).
使用方法
-
Set width and height
Any positive numbers. Common: 800×600, 1200×630 (OG image), 1500×500.
-
Pick colors
Background and text. High contrast reads best.
-
Copy the data URL or SVG
Use the data URL in <img>, the SVG inline in your markup.
示例
OG image (1200×630)
The recommended size for OpenGraph and Twitter cards.
