## Customize the Blazor DataGrid frozen header cells

The **.e-leftfreeze** class styles all the left frozen header cells in the Blazor DataGrid.

```css

.e-headercell.e-leftalign.e-leftfreeze {
background-color: lightgreen;
}

.e-headercell.e-rightalign.e-leftfreeze {
background-color: lightgreen;
}

```

The **.e-rightfreeze** class styles all the right frozen header cells in the Blazor DataGrid.

```css

.e-headercell.e-rightalign.e-rightfreeze {
background-color: lightblue;
}

```

The **.e-fixedfreeze** class styles all the fixed frozen header cells in the Blazor DataGrid.

```css

.e-headercell.e-leftalign.e-fixedfreeze {
background-color: lightgrey;
}

```

Properties such as **color**, **background-color**, **font**, and alignment can be adjusted to align with the grid design.
