CSS modified after opening a modal dialog that has loaded external HTML content

Within my ASP.NET MVC project, I am utilizing a tab wizard. On one of the tabs, I trigger a modal dialog by loading HTML content from an external API. However, once I close the wizard and navigate to the next tab, the table style (specifically border color and thickness) is impacted by the styling from the HTML in the modal dialog. I attempted overriding the styles for td, th, and borders using !important, but this approach did not yield desired results. Given these constraints, what steps should I take? It is important to note that modifying the CSS of the external HTML source being returned is not an option. I also experimented with applying styles via JavaScript after closing the modal, however, it had minimal impact. Any suggestions?

Below are snippets of my CSS attempts and the relevant HTML code:

.table > tbody > tr > td, .table > tbody > tr > th, .table > tfoot > tr > td, 
.table > tfoot > tr > th, .table > thead > tr > td, .table > thead > tr > th {
    padding: 8px;
    line-height: 1.42857 !important;
    vertical-align: top !important;
    border-top: 1px solid #e7ecf1 !important;
    vertical-align: middle !important;
}

<table class="table table-striped table-hover">
    <thead>
        <tr>
            <th>Aaaaaa </th>
            <!-- code omitted for brevity -->
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr>
                <td>Bbbbbbbbb</td>
                <!-- code omitted for brevity -->
            </tr>
        }
    </tbody>
</table>

Answer №1

If you want to remove the <style> tag when closing the modal, you can use the following function:

// Function to be called on modal close
function removeStyleTag() {
  const styleElement = document.querySelector('.modal style');
  // Adjust selector based on your specific scenario

  // Remove the <style> tag from the DOM
  styleElement.parentElement.removeChild(styleElement);
}
