How to Always Show Scrollbar

CSS - Overflow: Scroll; - Always show vertical scroll bar?

Just ran into this problem myself. OSx Lion hides scrollbars while not in use to make it seem more "slick", but at the same time the issue you addressed comes up: people sometimes cannot see whether a div has a scroll feature or not.

The fix: In your css include -

::-webkit-scrollbar {
  -webkit-appearance: none;
  width: 7px;
}

::-webkit-scrollbar-thumb {
  border-radius: 4px;
  background-color: rgba(0, 0, 0, .5);
  box-shadow: 0 0 1px rgba(255, 255, 255, .5);
}

/* always show scrollbars */
::-webkit-scrollbar {  -webkit-appearance: none;  width: 7px;}
::-webkit-scrollbar-thumb {  border-radius: 4px;  background-color: rgba(0, 0, 0, .5);  box-shadow: 0 0 1px rgba(255, 255, 255, .5);}

/* css for demo */
#container {  height: 4em;  /* shorter than the child */  overflow-y: scroll;  /* clip height to 4em and scroll to show the rest */}
#child {  height: 12em;  /* taller than the parent to force scrolling */}

/* === ignore stuff below, it's just to help with the visual. === */
#container {  background-color: #ffc;}
#child {  margin: 30px;  background-color: #eee;  text-align: center;}

<div id="container">  <div id="child">Example</div></div>

How to always show the vertical scrollbar in a browser?

jQuery shouldn't be required. You could try adding the CSS:

body    {overflow-y:scroll;}

This works across the latest browsers, even IE6.

How to always show scrollbar

As of now the best way is to use android:fadeScrollbars="false" in xml which is equivalent to ScrollView.setScrollbarFadingEnabled(false); in java code.

make a scrollbar always visible in a div - chrome

Just having the scrollbar visible will not allow you to react to the user trying to scroll down. So you will need to actually make the content flow outside of the area and detect the scroll.

Try this:

#scrollarea-invalid {
overflow-y: scroll;
height: 350px;
}
#scrollarea-content{
  min-height:101%;
}

<div id='scrollarea-invalid'>
  <div id='scrollarea-content'></div>
</div>

                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="Auto"/>
                        </Grid.ColumnDefinitions>

                        <ScrollBar x:Name="HorizontalScrollBar" IsTabStop="False" Maximum="{TemplateBinding ScrollableWidth}" Orientation="Horizontal" Grid.Row="1" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{TemplateBinding HorizontalOffset}" ViewportSize="{TemplateBinding ViewportWidth}"/>
                        <Border x:Name="ScrollBarSeparator" Background="{ThemeResource SystemControlPageBackgroundChromeLowBrush}" Grid.Column="1" Grid.Row="1"/>
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Then reference it in your scrollviewer

<ScrollViewer Style="{StaticResource MyScrollViewerStyle}" Height="680" Width="480" HorizontalAlignment="Center" VerticalAlignment="Center">

    <Image Source="/Assets/wallpaper.jpg"/> <!-- or your items -->

</ScrollViewer>

Making the main scrollbar always visible

html {
    overflow: -moz-scrollbars-vertical; 
    overflow-y: scroll;
}

This makes the scrollbar always visible and only active when needed.

Update: If the above does not work then just using this may.

html {
    overflow-y:scroll;
}

Making the main scrollbar always visible - without scroll

The behavior works as expected on Windows machines, but it appears MacOS and iOS have their own handling of scrollbars. You can see this issue addressed in this question.

Some of the options listed within the answer are to style the scrollbar manually like so:

.frame::-webkit-scrollbar {
    -webkit-appearance: none;
}

.frame::-webkit-scrollbar:vertical {
    width: 11px;
}

.frame::-webkit-scrollbar:horizontal {
    height: 11px;
}

.frame::-webkit-scrollbar-thumb {
    border-radius: 8px;
    border: 2px solid white; /* should match background, can't be transparent */
    background-color: rgba(0, 0, 0, .5);
}

.frame::-webkit-scrollbar-track { 
    background-color: #fff; 
    border-radius: 8px; 
} 

You can also use javascript to manually scroll the scrollbar on page load, just a single pixel. Like this:

$('#scrollable-section').scrollTop(1).scrollTop(0);
