I want to add color and border to a javascript variable using css. Below is my code;
var msg = "OK"; //i want this to colored and bordered with green.
msg = "Conflict"; // i want this to be colored and bordered with red.
I tried another answer from other questions but it doesn't seem to work with me.
If you're just trying to add styles to a JavaScript variable you can't do that, and I don't understand what you would hope to achieve by doing that.
I am therefore going to assume you want to add styles to an html element that you have extracted as a JavaScript variable like so
let msgElement = document.getElementById('msg')
let msg = "OK"
msgElement.innerHTML = msg
In this case, you can add styles to the element like so
msgElement.style.color = "red"
msgElement.style.border = "2px solid red"
In your example, when you change the value of msg to "Conflict", you are doing just that - changing it. You can't have two separate values held by the same variable.
As one of the comments says, this is basic web development, so I would advise some further reading, or an online course such as those provided by Codeacademy
As the other answers state, you can't apply a CSS rule to a variable. You can, however, do something like this:
<html>
<head>
<style>
.redgreen {border-style: solid; border-color: green; color: red;}
</style>
<script>
function foo() {
let msg = "<div class='redgreen'>Hello, world!</div>";
document.getElementById("themsg").innerHTML = msg;
}
</script>
</head>
<body onload='foo();'>
<p id='themsg'>Your message here</p>
</body>
</html>
That is, define "msg" as an HTML element instead of a text string.
.innerHTML to add a div to a p element is not a good idea as p elements shouldn't really have any children other than inline elements such as span
innerHTML like that. But you're right, for the purpose of this question it doesn't matter.You can't add CSS to a javascript variable.
if you are create element using javascript
html:
<div class="parent-div">
</div>
js:
var msg = "OK";
element = document.createElement('p');
// Give the new element some content and css
element.innerHTML = msg;
element.style.color = 'green';
element.style.border = "1px solid red";
// append element to parent div
document.querySelector('.parent-div').appendChild(element);
Just do without javascript
html:
<div class="parent-div">
<p class="child-one">OK</p>
<p class="child-two">Conflict</p>
</div>
css:
.parent-div .child-one {
color: red;
border: 1px solid green;
}
.parent-div .child-two {
color: green;
border: 1px solid red;
}
var msg = "OK"it means that the variablemsg, in your computer's memory somewhere, holds the value"OK". Nothing else. It has no concept of color or size or psychology or anything. It's just a value. But you can write this value to your HTML document, like in a<div>or something, and then use CSS to style that div and give it a color and a size. This is day 1, hour 1 of web development, I suggest you take some very basic tutorial :)
