Styling JavaScript strings with CSS - JavaScript/CSS Integration

I am trying to display a tooltip on hover using the data-tip attribute, but I am facing limitations with it only accepting strings. As a workaround, I have adopted the following approach:

var title = "Hello World";
var online: "Last Online 2 mins ago".
    <div>
        <span data-tip={title +" \n " +online} data-tip-always>{title}</span>
    </div>

However, I am now encountering an issue on how to style {title} as bold and set {online} font-size smaller than {title}.

Here is my updated code:

const titles = `<span class="title">Hello</span>`;
const online = `<span class="online">You are online</span>` ;
<span data-tip={`${titles}\n${online}`} data-html="true" data-tip-always>{title}</span>

As a result, I am currently seeing this formatting:

Initially, I attempted to implement this in JSX to apply colors and fonts, however, I struggled to find a way to incorporate JSX/HTML within a data-tip. Is there a method to apply CSS styles directly to strings?

Thank you.

The data-tip attribute in React-tooltip can only accept strings, but you can use the data-for attribute to reference a <ReactTooltip> component that can contain any content:

var title = 'Hello World';
var online = 'Last Online 2 mins ago';

ReactDOM.render(
<div>
  <span data-tip data-for="unique-tooltip-id" data-tip-always>{title}</span>
  <ReactTooltip id="unique-tooltip-id">
    <div className="tooltip-title">{title}</div>
    <div className="tooltip-online">{online}</div>
  </ReactTooltip>
</div>,
document.getElementById("react")
);

.tooltip-title {
  font-weight: bold;
}

.tooltip-online {
  font-size: 80%;
}

<script src="https://cdn.jsdelivr.net/gh/wwayne/react-tooltip@master/standalone/react-tooltip.min.js"></script>

<div id="react" style="position:absolute; left: 50%; top: 50%; transform: translate(-50%, -50%);"></div>

If you use es6 notation, you can turn it into a template string.

Define your variables like this:

const title = `<span class="title">Hello</span>`
const online = `<span class="online">You are online</span>`

Then update your code to include the variables inside the string:

<div>
   <span data-tip={`${title}\n${online}`} data-tip-always>{title}</span>
</div>

This way, you have the flexibility to interpolate any variables within the template string and easily access them from the Element.dataset.
