Background Customization of Tabs in Shiny tabPanel
Problem:
In a Shiny application, you wish to modify the background colors and text colors of the tabs in a tabPanel, specifically:
- When a tab is selected, its background should turn black with white text.
- Unselected tabs should display a white background with black text.
Solution:
To achieve this, you can utilize CSS styles as follows:
ui <- shinyUI(fluidPage(
tags$style(".nav-tabs {
background-color: aqua; color:black}
.tabbable > .nav > li > a {
background-color: #006747;
color: white;
}
.nav-tabs-custom .nav-tabs li.active:hover a, .nav-tabs-custom .nav-tabs li.active a {
background-color: transparent;
border-color: transparent;
}
.nav-tabs-custom .nav-tabs li.active {
border-top-color: #FFF;
}"),
tabsetPanel(
tabPanel(
title = "Hello",
textInput(inputId = "text", label = "Input")
),
tabPanel(
title = "World"
)
)
)
)
Explanation:
This CSS code is implemented as follows:
- The .nav-tabs class sets the background of all tabs to aqua and black text.
- The .tabbable > .nav > li > a class modifies the background and text color of all tabs to black and white, respectively.
- The .nav-tabs-custom .nav-tabs li.active:hover a and .nav-tabs-custom .nav-tabs li.active a classes ensure that the background of the active tab remains transparent while hovering or clicking.
- The .nav-tabs-custom .nav-tabs li.active class sets the border-top color of the active tab to white.
This comprehensive solution allows you to customize the appearance of tabs in a shiny tabPanel to meet your specific requirements.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
