I do a lot of fiddling around in the console for things like these, and the advent of ES2016 for..of loops makes this quite a lot simpler nowadays: for (let a of document.querySelectorAll('a')) { a.style.fontWeight = 'normal' } Alternatively, you can use the more functional: Array.from(document.querySelectorAll('a')).map(a => a.style.fontWeight = 'bold') If your browser supports the spread operator you could equivalently do: [...document.querySelectorAll('a')].map(a => a.style.fontWeight = 'bold')
