Order of precedence for controlling the outer background color

I am implementing a hierarchy of spans to define different layers of annotations:

<span class="eventRel" id="e12-e32">
    <span class="event">
        <span class="hl" id="moh">
            soluzione
            <span style="width:500px;">
                tokenid: 11
            </span>
        </span>
    </span>
</span>

Next, I have various controllers in place to highlight the token using the background property (in this case: soluzione) with different colors.

However, my code works perfectly when there is only one span layer above the class="hl".

Sometimes, there are instances where there are more than 3 spans above the class="hl".

To make it work, I use the following code snippet:

document.getElementById('e12-e32').style.backgroundColor='white';

This solution only works under specific conditions:

<span class="event">
    <span class="hl" id="moh">
        soluzione
        <span style="width:500px;">
            tokenid: 11
        </span>
    </span>
</span>

If you can provide assistance in this matter, it would be greatly appreciated. Thank you in advance.

Now, to achieve the desired result of highlighting the word soluzione, I need to apply the following style:

  <span class="eventRel" id="e12-e32" style="background-color:yellow;">
    <span class="event">
        <span class="hl" id="moh">
            soluzione
            <span style="width:500px;">
                tokenid: 11
            </span>
        </span>
    </span>
</span>

Answer №1

It is possible that there was a misunderstanding with your problem, but to target all child elements, you can utilize the following code snippet:

  document.querySelectorAll(".e12-e32")

Answer №2

i utilized inline styles for my design, here is a piece of code that you might find useful:

    <span class="event">
    <span class="hl"  style="background-color:yellow;">
        solution
        <span style="width:500px;background-color:red;">
            tokenid: 11
        </span>
    </span>
</span>

Answer №3

In the scenario I encountered, my aim was to emphasize the word soluzione by assigning it to an annotation layer contained within a span element. The solution turned out to be to assign a unique class name to each annotation layer (span) and then apply the desired styling to that class. My mistake in implementing this was attempting to use an id to identify the spans, which led to duplications of the id.

Therefore, it is advisable to always first investigate any style discrepancies by checking for id duplications when making adjustments. Failure to do so may result in unnoticed errors, with changes only being applied to the first element sharing that particular id!
