Here are two ways the zoom level can be altered with Java (one is for Chrome and the other is for Firefox): Chrome Because of this, the Keys.NULL used in my solution is required. The WebElement's sendKeys() is different from the one in Actions. Note that the naïve approach ndKeys(Keys.CONTROL, Keys.ADD) ĭoesn't work, because the Ctrl key is released in this sendKeys() method. sendKeys(html, Keys.CONTROL, '0', Keys.NULL) sendKeys(html, Keys.CONTROL, Keys.ADD, Keys.NULL)Īgain, don't forget to reset the zoom afterwards: new Actions(driver) Or, you can use the Advanced User Interactions API like this (again, Java code, but it should work the same in C#): WebElement html = driver.findElement(By.tagName('html')) (since I realized C# bindings don't have the Keys.chord() method)

Use cautiously and when you're done, reset the zoom back to 100%: ndKeys(Keys.chord(Keys.CONTROL, '0')) ndKeys(Keys.chord(Keys.CONTROL, Keys.ADD)) You can use the Keys.chord() method: WebElement html = driver.findElement(By.tagName('html')) Beware that Selenium assumes the zoom level is at 100%! For example, IE will refuse to start (throws an Exception) when the zoom level is different, because the element locating depends on this and if you changed the zoom level, it would click on wrong elements, at wrong places.
