> # Remarks

> ### Differences between HtmlPanel and HtmlLabel

> The major differential to use HtmlPanel or HtmlLabel is size and scrollbars.
> If the size of the control depends on the html content the HtmlLabel should be used.
> If the size is set by some kind of layout then HtmlPanel is more suitable, also shows scrollbars if the html contents is larger than the control client rectangle.
> - HtmlPanel has scrollbars support
> - HtmlLabel can be autosized
> - HtmlLabel can have transparent background

> ### AutoSize

> The label size will not change by the html content. MaximumSize and MinimumSize are ignored.
> AutoSize = true
> The width and height is adjustable by the html content, the width will be longest line in the html, MaximumSize.Width will restrict it but it can be lower than that.
> AutoSizeHeightOnly = true
> The width of the label is set and will not change by the content, the height is adjustable by the html content with restrictions to the MaximumSize.Height and MinimumSize.Height values.
