# CellStyle
```csharp
public sealed class CellStyle
```
Namespace `SharpCell` ยท package `SharpCell`
How a cell looks in Excel: font, fill, borders, alignment and protection (locked, formula hidden). The number format is not part of it; see [Cell.NumberFormat](SharpCell.Cell.md#numberformat). Styles play no part in calculation. A record: styles compare by value, and `with` makes a changed copy, such as `style with { Fill = CellColor.FromRgb(0xFFFF00) }`.
## Constructors
### CellStyle()
```csharp
public CellStyle()
```
A style like [CellStyle.Default](SharpCell.CellStyle.md#default); set properties in an initializer.
## Properties
### BottomBorder
```csharp
public CellBorder? BottomBorder { get; init; }
```
The bottom edge of the border; null for none.
### Default
```csharp
public static CellStyle Default { get; }
```
The style of a new workbook's cells: [CellFont.Default](SharpCell.CellFont.md#default), no fill, no borders, General alignment at the bottom.
### Fill
```csharp
public CellColor? Fill { get; init; }
```
The colour the cell is filled with; null for none. Only solid fills are read from files.
### Font
```csharp
public CellFont Font { get; init; }
```
The font.
### FormulaHidden
```csharp
public bool FormulaHidden { get; init; }
```
Whether the cell's formula is hidden from the formula bar while its sheet is protected.
### HorizontalAlignment
```csharp
public CellHorizontalAlignment HorizontalAlignment { get; init; }
```
Where the text sits across the cell. [CellHorizontalAlignment.General](SharpCell.CellHorizontalAlignment.md#general) is Excel's default: numbers right, text left, logical values and errors in the middle.
### Indent
```csharp
public int Indent { get; init; }
```
The indent, in steps of the width of three characters of the default font; 0 to 250.

```
The left edge of the border; null for none.
### Locked
```csharp
public bool Locked { get; init; }

### RightBorder
```csharp
public CellBorder? RightBorder { get; init; }
```
The right edge of the border; null for none.
### TopBorder
```csharp
public CellBorder? TopBorder { get; init; }

The top edge of the border; null for none.
### VerticalAlignment
```csharp
public CellVerticalAlignment VerticalAlignment { get; init; }

### WrapText
