I'm having trouble adjusting the font size using a variable in my code. Can anyone pinpoint the issue?
<div id = "letter">
<span>A</span>
<span>l</span>
<span>p</span>
<span>h</span>
<span>a</span>
<span>b</span>
<span>e</span>
<span>t</span>
<div>
var list = document.getElementsByTagName("span");
var size = 20;
for (i=0; i<list.length; i++) {
size+=5;
list[i].style.fontSize = "sizepx";
};
alert(list.length);
http://example.com/code-sample
list[i].style.fontSize = size + "px";
Check out this useful example in a fiddle http://jsfiddle.net/yRLN3/3/
var items = document.getElementsByTagName("span");
var textSize = 20;
for (let j=0; j<items.length; j++) {
textSize+=5;
items[j].style.fontSize = textSize + 'px';
};
alert(items.length);
There was a typo in your typing
The code should be: list[i].style.fontSize = size + "px";
The variable 'size' is supposed to be an integer, but in your code it was treated as a string because of the quotes.
