In Xamarin Forms, to change the style of multiple controls of the same type, you have to use Style classes.

You can define a style at Application level or page level. Here is a style definition at page level:

<ContentPage ....>

    <ContentPage.Resources>
        <Style x:Key="myBigButtonStyle" TargetType="Button">
            <Setter Property="Foreground" Value="Black" />
            <Setter Property="BorderThickness" Value="10" />
        </Style>

    </ContentPage.Resources>
    . . .

To apply the style:

<Button x:Name="button1" Style="{StaticResource myBigButtonStyle}" ... />

But if you want to apply this style to ALL the buttons of your page, just remove the resource button style KEY:

<Style TargetType="Button">
    <Setter Property="Foreground" Value="Black" />
    <Setter Property="BorderThickness" Value="10" />
</Style>

then, do not apply any style to your buttons:

<Button x:Name="button1" ... />

All the style class documentation can be found here: Microsoft styles documentation

Syntax is not the same as html. But in the latest versions of Xamarin you can use CSS files to apply styles. But this option is still limited: Using CSS files with Xamarin Forms documentation
