Value

A string.

When set to the null value, that null value is converted to the empty string (""), so csd.cssFloat = null is equivalent to csd.cssFloat = "".

Example

In the below example, the stylesheet contains a single rule for .box, which has the float property with a value of left. This value will be returned by cssFloat. We then set the value to "right" using cssFloat, and return the new value.

.box {
  float: left;
  inline-size: 300px;
}

let myRules = document.styleSheets[0].cssRules;
let rule = myRules[0];
console.log(rule.style.cssFloat); // "left"
rule.style.cssFloat = "right";
console.log(rule.style.cssFloat); // "right"
