Troubleshooting the Ineffectiveness of the CSS Custom Property Url in Asp .Net

Working on styling some cards within an MVC project, I have a custom property in my CSS file called "--bg-img" which is defined as follows:

 background-image: linear-gradient(rgba(0, 0, 0, var(--bg-filter-opacity)), rgba(0, 0, 0, var(--bg-filter-opacity))), var(--bg-img);

In my cshtml file, the code appears like this:

<a class="card-posting-link posting-links" asp-action="details" asp-route-id="@item.Id" style="--bg-img: url('../../wwwroot/Uploads/@item.ImagePath')">

Everything works fine in VS Code, for example:

<a class="card-posting-link posting-links" href="/#/" style="--bg-img: url(/Assets/image.jpeg)">

I have tried using:

~/Uploads

~/wwwroot/Uploads

and various other methods to retrieve the images, but nothing seems to be working.

Answer №1

To solve the issue, I included the c# Url.Content before appending the css URL, as shown below:

href="@Url.Content("~/wwwroot/Uploads/@item.ImagePath")" />
