## Protocol.CSS.CSSStyleSheetHeader.isMutable property
Whether this stylesheet is mutable. Inline stylesheets become mutable after they have been modified via CSSOM API. <link> element's stylesheets become mutable only if DevTools modifies them. Constructed stylesheets (new CSSStyleSheet()) are mutable immediately after creation.
<b>Signature:</b>
```typescript
isMutable: boolean;
```
