Question: here is my html:

```
<div id="banner" style="background-image: url("img/banner.jpg")">
  <img src="img/logo.png" alt="logo" />
</div>

```

and this is my css:

```
#banner {
  width: auto;
  height: 100vw;
  background: url("/img/banner.jpg");

I want the banner.jpg to be the background of that div with full viewport fill... what to do?

Answer: 
**UPDATE**
With regards to your update - you need to add the following to your **ApplicationDbContext**:

```
 protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Hotel>().Property(x => x.Longitude).HasPrecision(11, 6);
    }

```

Try adding a mapping:

```
modelBuilder.Entity<Hotel>().Property(x => x.Longitude).HasPrecision(11, 6);

```
