How to draw a line with color in shiny application
r, shiny
Solution
Shiny exposes a lot of control over the look and feel of the application, but it happens that the color of `hr` isn't one of of them. So you'd need to dig down into CSS to control the appearance of the element. You can do this by using `includeCSS` in Shiny to add a stylesheet that you can use to control the look of your app. The easiest way, however, would likely just be to add the CSS onto your `hr` element directly.
HTML('<hr style="color: purple;">')
(EDIT) Note that, while this would work for most elements, `hr` don't respect the `color` property. `hr`s behave strangely: Changing the color of an hr element
Here you're modifying the CSS `color` property of your `hr` element. See https://developer.mozilla.org/en-US/docs/Web/CSS/color
Also note that you can use `hr(style="...")` instead of constructing the raw HTML, if you prefer. I find that constructing everything with Shiny tags makes the code a little easier to read in most cases, but YMMV.
Problem
This may be a simplest thing for lot of people, but I'm struggling with it. I'd like to draw a line with color using html tag "hr" This is what I have tried so far in ui.R file : ``` HTML("<hr color='purple' >") HTML('<hr color="purple" >') hr( color="purple" ) ``` None of them worked - any suggestions please?
