Preserving Line Breaks in Template Literals When Adding to HTML with JavaScript

When working with JavaScript and HTML, it's common to utilize template literals for string creation. However, a common challenge arises when you wish to maintain the formatting of those strings, especially when it comes to keeping line breaks intact. In this post, we’ll delve into how to achieve this through proper styling and coding techniques.

The Problem: Losing Line Breaks

Imagine you're creating a string using a template literal in JavaScript, and you want to display it on your webpage. Template literals allow for easy multi-line strings, but when you try to render them in HTML, the line breaks tend to vanish. Here’s an example:

In the above code, if str is rendered directly into HTML, you won’t be able to see the line breaks, leading to unformatted text. So how can you ensure that those breaks are preserved?

The Solution: Applying CSS Styles

Step 1: Style Your Div Element

To make sure the line breaks are visually represented in HTML, you need to use the CSS property white-space. This property controls how whitespace, including line breaks, is handled within an element. Specifically, you'll want to use the value pre-wrap, which respects both the text formatting and line breaks.

Step 2: Update Your Code

Here’s how you can modify the code to include the necessary styling:

In this update, note how the div that holds str is styled with white-space: pre-wrap;. This tells the browser to render the line breaks properly.

Final HTML Structure

Make sure your HTML structure is intact as well:

Recap of Key Points

Use Template Literals: They allow for easy creation of multi-line strings in JavaScript.

Apply CSS Style white-space: pre-wrap;: This is crucial for preserving line breaks and formatting in your displayed text.

Check Your HTML Structure: Ensure that the output element is set up correctly to prevent any potential issues.

By following these simple steps, you can easily maintain the formatting of text created using template literals, resulting in a cleaner and more visually appealing presentation on your web page.

Conclusion

Dealing with line breaks in JavaScript can initially seem daunting, but with the right CSS styling, you can ensure that your template literals display as intended. Don’t let formatting issues hinder your web development process; confidently use template literals to create structured, well-formatted text for your users!
