How to implement row hover in Blazor wasm

<p>I have a Blazor table component that changes based on the number of variable rows in a collection: </p>
<pre class="brush:php;toolbar:false;"><table id="MyTable" class="table table-hover">
<thead>
<tr>
<th>Project name</th>
<th>Description</th>
<th>Uploader</th>
<th>Upload Date</th>
</tr>
</thead>
@foreach (var item in Items)
{
<tbody>
<tr>
<th>@item.Name</th>
<th>@item.Description</th>
<th>@item.UserName</th>
<th>@item.UploadDate.ToString("dd-MM-yyyy")</th>
<th><button type="button" class="btn btn-primary" @onclick="() => DoSomething()">Do Work</button></th>
</tr>
</tbody>
}
</table></pre>
<p>What I need to do is, when the mouse is hovering over a row,<em>only</em>that specific element of that row becomes enabled. </p>
<p>For example, if this table has 10 rows (1-10), when I hover over row 1, only the button for row 1 should be visible and clickable. Other buttons whose parent row has no hover should not be enabled. </p>
<p>In Blazor, how do I enable only the <em>buttons on that specific row</em> when hovering over a row? </p>
As mentioned in the comments, there are some reasons why you might not want to show child elements on mouseover: it relies on the user using the mouse. Alternatively, the entire row can be made clickable, which may provide a better user experience.
Though for the sake of completeness, here is how to solve the problem I asked:
In the Razor page, add CSS Id selectors for the row (parent) and button (child) HTML tags:
We can then use CSS to apply styles to the button (child) on hover over the row (parent):
Depending on your use case, you may want to apply different styles. For example, use display: none; instead of visibility: hidden;
