I am looking to create an array containing the font sizes of all the p tags in my HTML document. How can I specifically target only the p elements and not their parent elements?
I am looking to create an array containing the font sizes of all the p tags in my HTML document. How can I specifically target only the p elements and not their parent elements?
If you want to retrieve font-size values from HTML elements, you can try using the following code:
Find more information here: https://developer.mozilla.org/en-US/docs/Web/API/Window/getComputedStyle
var paragraphs = document.getElementsByTagName("p");
var fontSizes = [];
for(var i=0; i<paragraphs.length; i++) {
var style = window.getComputedStyle(paragraphs[i], null);
fontSizes.push(style['font-size']);
}
console.log(fontSizes);
Check out this demo for a live example: http://jsfiddle.net/1us76t0g/1/
Even if there are no inline styles defined, this method allows you to gather font-size values into an array.
