Styling in developer tools

You can manipulate or alter HTML styling using built-in CSS of the website or by creating custom styles.

/*Clear out any existing css.*/ document.head.innerHTML = '' /*Change font to Arial of the text*/ document.body.style.fontFamily = “Arial” /*Change background colour of page*/ document.body.style.backgroundColor = 'rgb(128, 0, 128)' /*Change background colour of text*/ document.body.style.color = 'white'
