Bug detected in Firefox: Hyperlinks not functioning properly when placed outside block

Previously, I heard that Firefox had a significant issue with links wrapping around block elements. Recently, this problem has caused some challenges for me as well.

About 20% of the time, for unknown reasons, when I modify this code (keep in mind that all elements are defined as block elements in my stylesheet):

<li>
  <a href="product.htm">
    <img src="product-image.jpg" width="100" height="100" alt="Product image" />
    <h2>Product title</h2>
    <p>Product description</p>
  </a>
</li>

To look like this:

<li>
  <a href="product.htm">
    <img width="100" height="100" alt="Product image" src="product-image.jpg">
  </a>
  <h2>
    <a _moz-rs-heading="" href="product.htm">Product title</a>
  </h2>
  <p></p>
  <p>
    <a href="product.htm">Product description</a>
  </p>
</li>

This modification completely messes up how the elements are displayed according to the stylesheet. I rely on the a element to create a large link containing the product image, title, and description in a webshop product list.

I really need those large links but can't seem to find another way to achieve this. Any suggestions on what I should do?

Answer №1

I'm not entirely certain about the reliability of xhtml.com as a source, but according to them, the a tag should only include:

  • Inline elements, excluding the a itself, at any level
  • Text

An alternative approach could involve restructuring your HTML for better clarity (e.g., avoiding nesting block-level elements within inline-level ones). Consider having a single hyperlink for the product, perhaps within the h2 heading or around the image. Then utilize JavaScript to detect clicks on any li element and load the link accordingly.

Does this strategy seem logical? Check out an example here.

Answer №2

Are all examples of these list items consistently encoded? (Check: put everything through the validator.) You mentioned it only occurs ~20% of the time, so you should first confirm if the ones that break have any distinguishing features. This seems to be some sort of over-correction by the browser. A search for _moz-rs-heading brings up several older posts like this one. (Keep in mind the bug mentioned there has been resolved.) However, in a few instances, individuals found out that their actual <a> tags were faulty, they just weren't aware of it, and the adjustments you're observing were Firefox's way of handling it more gracefully.

Answer №3

I encountered a similar issue where the HTML would appear differently each time I refreshed the page in Firefox. The <a>..</a> tags were breaking into multiple smaller

<a>..</a><a>..</a>
blocks in unpredictable ways, leading to incorrect display almost every time.

A helpful resource suggested adding a <div> directly under the <a>, which was already present in the code provided by my web designer but did not resolve the issue.

To fix this problem, I replaced the <div> with a

<span style="display:block">
and this successfully resolved the display inconsistencies.

<a ...>
   <span style="display:block">
      ...
   </span>
</a>
