Suppose I have a JavaScript function that displays an error using the following code
document.getElementById("ID").innerHTML = "This is your error";
Now, if I wish to customize the error message by changing its text color and repositioning it on the page, what steps should I take? Despite my efforts to search for relevant information, I am unable to find any guidance.
By using innerHTML, you can easily insert HTML elements into your code. For example, adding a span tag with a custom CSS class.
Incorporating JS/CSS and HTML
document.getElementById('error-message').innerHTML = "<span class='error'>my error</span>";.error {
color: red;
font-size: 24px;
}<div id="error-message"></div>Take a look at this solution, it should meet your requirements:
document.getElementById("ID").innerHTML = "This is your error";
var sheet = document.createElement('style')
sheet.innerHTML = "div {color:red;overflow:hidden;}";
document.body.appendChild(sheet);
Include the following line in your span code:
#myspan{float:left;}
