Did you know that you can change the browser's default text highlight (selection) background color using CSS? For example:
::selection {
background: #ffb7b7;
}
Find out more about the browser/OS specific default background color when selecting text here. Is there a way to access this default value using JavaScript or Dart?
It is not possible to change the default selection background color.
When using
getComputedStyle(yourElement, '::selection').backgroundColorgetComputedStyle(yourElement, '::-moz-selection').backgroundColortransparent. The browser will not override the operating system's default selection color. However, if you manually set it to transparent, the default os value will be overridden.
Browsers likely do not have access to the operating system's default preferences, and even if they do, it is unlikely that websites would have such easy access to them.
According to information found at , you have the option to utilize CSS system colors by visiting https://www.w3.org/TR/2010/PR-css3-color-20101028/#css2-system, even though they are considered deprecated, they still function properly.
