CSS Issues in Mobile View: How to Fix Nested Tables for a Better User Experience

When designing web pages, ensuring a seamless experience across all devices is crucial. One common issue developers encounter is when content gets distorted or poorly formatted on mobile devices. A specific problem arises when dealing with nested tables, especially when using line breaks to separate multiple pieces of information, such as contact numbers.

In this guide, we will explore the issue of a nested table that stacks rows on mobile view and leaves excessive space in the contact column. We'll also provide a solution to properly format your CSS without disturbing the alignment of the contact numbers.

The Problem: Misaligned Nested Tables in Mobile View

What’s Happening?

You have a nested table displaying three columns: Name, Email, and Contact. In the contact column, there are two contact numbers separated by a <br>. When viewed on a mobile device, the table's structure collapses into a single column where the excessive space between the column headings becomes distractions, making the user experience less than ideal.

The Solution: Adjusting CSS for Better Alignment

Step-by-Step Guide

The goal here is to move the "Contact" heading closer to the actual contact numbers, without affecting the display of the numbers themselves. Since inline elements do not take margins, you can achieve this by adjusting the vertical alignment properties in CSS.

Add Media Query for Mobile Devices
You can define styles that will only apply when the screen width is below a certain size, in this case, 500 pixels.

Understanding the Code

Here, we are creating a CSS media query that targets devices with a screen width of up to 500 pixels.

The td::before selector refers to the pseudo-element that allows us to display content before the actual table data.

By using vertical-align: top;, we make sure that the heading aligns neatly without affecting the contact numbers, which remain below it.

Implementing the Entire CSS & HTML Structure
Ensure your CSS and HTML structure is set up similar to this:

Result
By applying the given CSS fix, you will see that the space above the contact heading has been minimized, while the contact numbers remain properly positioned, enhancing readability and overall user experience.

Conclusion

Responsive design can often be challenging, particularly when working with tables containing nested elements. However, with a few adjustments in CSS, it’s entirely possible to maintain the integrity of your layout across devices. By taking advantage of media queries and proper vertical alignment, you can ensure that your tables look clean and professional, even on mobile screens.

Take the time to review your existing CSS and apply these principles to make sure your nested tables perform optimally on all devices!

Happy coding!
