Create a page that fills the window

fillPage(..., padding = 0, title = NULL, bootstrap = TRUE, theme = NULL)

Arguments

... Elements to include within the page.
padding Padding to use for the body. This can be a numeric vector (which will be interpreted as pixels) or a character vector with valid CSS lengths. The length can be between one and four. If one, then that value will be used for all four sides. If two, then the first value will be used for the top and bottom, while the second value will be used for left and right. If three, then the first will be used for top, the second will be left and right, and the third will be bottom. If four, then the values will be interpreted as top, right, bottom, and left respectively.
title The title to use for the browser window/tab (it will not be shown in the document).
bootstrap If TRUE, load the Bootstrap CSS library.
theme URL to alternative Bootstrap stylesheet.

Description

fillPage creates a page whose height and width always fill the available area of the browser window.

Details

The fluidPage and fixedPage functions are used for creating web pages that are laid out from the top down, leaving whitespace at the bottom if the page content's height is smaller than the browser window, and scrolling if the content is larger than the window.

fillPage is designed to latch the document body's size to the size of the window. This makes it possible to fill it with content that also scales to the size of the window.

For example, fluidPage(plotOutput("plot", height = "100%")) will not work as expected; the plot element's effective height will be 0, because the plot's containing elements (<div> and <body>) have automatic height; that is, they determine their own height based on the height of their contained elements. However, fillPage(plotOutput("plot", height = "100%")) will work because fillPage fixes the <body> height at 100% of the window height.

Note that fillPage(plotOutput("plot")) will not cause the plot to fill the page. Like most Shiny output widgets, plotOutput's default height is a fixed number of pixels. You must explicitly set height = "100%" if you want a plot (or htmlwidget, say) to fill its container.

One must be careful what layouts/panels/elements come between the fillPage and the plots/widgets. Any container that has an automatic height will cause children with height = "100%" to misbehave. Stick to functions that are designed for fill layouts, such as the ones in this package.

Examples

fillPage( tags$style(type = "text/css", ".half-fill { width: 50%; height: 100%; }", "#one { float: left; background-color: #ddddff; }", "#two { float: right; background-color: #ccffcc; }" ), div(id = "one", class = "half-fill", "Left half" ), div(id = "two", class = "half-fill", "Right half" ), padding = 10 )
<style type="text/css"> .half-fill { width: 50%; height: 100%; } #one { float: left; background-color: #ddddff; } #two { float: right; background-color: #ccffcc; } </style> <div id="one" class="half-fill">Left half</div> <div id="two" class="half-fill">Right half</div>
fillPage( fillRow( div(style = "background-color: red; width: 100%; height: 100%;"), div(style = "background-color: blue; width: 100%; height: 100%;") ) )
<div class="flexfill-container flexfill-container-row" style="display:-webkit-flex;display:-ms-flexbox;display:flex;-webkit-flex-direction:row;-ms-flex-direction:row;flex-direction:row;width:100%;height:100%;"> <div class="flexfill-item" style="position:relative;-webkit-flex:1;-ms-flex:1;flex:1;width:100%;height:100%;"> <div class="flexfill-item-inner" style="position:absolute;top:0;left:0;right:0;bottom:0;"> <div style="background-color: red; width: 100%; height: 100%;"></div> </div> </div> <div class="flexfill-item" style="position:relative;-webkit-flex:1;-ms-flex:1;flex:1;width:100%;height:100%;"> <div class="flexfill-item-inner" style="position:absolute;top:0;left:0;right:0;bottom:0;"> <div style="background-color: blue; width: 100%; height: 100%;"></div> </div> </div> </div>
