How to change FontSize By JavaScript?
This code is not working
var span = document.getElementById("span");
span.style.font开发者_如何转开发size = "25px";
span.innerHTML = "String";
JavaScript is case sensitive.
So, if you want to change the font size, you have to go:
span.style.fontSize = "25px";
<span id="span">HOI</span>
<script>
var span = document.getElementById("span");
console.log(span);
span.style.fontSize = "25px";
span.innerHTML = "String";
</script>
You have two errors in your code:
document.getElementById
- This retrieves the element with an Id that is "span", you did not specify an id on the span-element.Capitals in Javascript - Also you forgot the capital of Size.
try this:
var span = document.getElementById("span");
span.style.fontSize = "25px";
span.innerHTML = "String";
Please never do this in real projects
