Variable Width Tooltips in a Fixed-Width Div

Tooltips are a common way to provide additional information or context in web applications. However, when you have a tooltip that pops up from a fixed-width div, things can become tricky — especially if you want the tooltip to be variable in width. This guide will address how to achieve a variable width tooltip that works seamlessly within a fixed-width container using a blend of CSS and jQuery.

Understanding the Problem

Imagine this scenario: You have a fixed-width element, such as a help icon, within a table cell. When users hover over this icon, a tooltip appears, but the tooltip’s text can be quite lengthy. The issue arises when the tooltip wraps based on the fixed width of the parent element rather than adapting to the width of its content. This not only disrupts the user experience but can also make it difficult for the tooltip to display comprehensively.

Key Requirements

The tooltip should be able to adjust its width based on its content.

The user should be able to hover over the tooltip and still dismiss it when they move the mouse away from both the tooltip and the icon.

Solution Overview

Although a pure CSS solution would be ideal, we've opted for a combination of jQuery to manage the dynamic styling of the tooltip’s width based on its content. Let’s explore the steps involved in this implementation.

Step 1: Setting Up Your HTML Structure

Here’s a basic structure for the tooltip and a table where the tooltip will be implemented:
