Editing the Calendar's Appearance

The look and feel ofDayBack is controlled through a CSS file which you can edit to alter the calendar's appearance and match the colors used in your own Salesforce deployment.

Where to make these CSS changes

You can enter your own CSS by logging into  Admin Settings and scrolling down to the CSS section in the left-hand sidebar. There you'll find a field into which you can paste your CSS changes:

Some common CSS customizations

How can I make changes to just the "Dark Mode" theme?

Preface your CSS classes with ".theme-dark" as in this change to the font size of an event:

.theme-dark .fc-event {
	font-size: 1em;

How can I increase the font size for events so they are easier to read?

Add the following lines. The first changes all the views except horizon; the second class changes the horizon view:

.fc-event {
	font-size: 1em;
.nub-content {
	font-size: 15px;

How can I hide the status or resource filters on the sidebar?

Add the following to hide the status filters
.filters-status {
	display: none;
or the following to hide the resource filters
.filters-resource {
	display: none;

How can I compress the height of status and resource filters to see more at once?

Add the following to change the height of the filters so that you can see more filter options without scrolling:
/* Compress the height of the filters in the sidebar */
.sidebar-filters .list-selector, .sidebar-filters .list-selector.selected, .sidebar-filters .list-selector-icon, .sidebar-filters .sidebar-drag-item{
  line-height: 20px;
  height: 20px;
.sidebar-filters .list-selector .calendarColor {
  height: 17px;
  margin-top: 2px;
.sidebar-filters .list-selector .fa-cog{
  font-size: 15px;

/* Adjust filters header block */
.sidebar-filters .header-block {
  width: 100%;
  height: 30px;
  line-height: 30px;
.sidebar-filters .header-block button {
  padding-top: 2px;

/* Adjust text filter container */
.sidebar-filters .search-wrapper {
  line-height: 20px;
  min-height: 25px;
.sidebar-filters .search-wrapper textarea{
  height: 17px !important;
  margin-top: 2px;
.sidebar-filters .search-wrapper .fa-search, .sidebar-filters .search-wrapper .fa-times{
  margin-top: 1px;

/* Adjust selected folder indicator */
.list-selector.is-filtered:before {
    bottom: 0px;
    height: 2px;

Can I hide the red line for the current time?

If you don't want to see that red line, you can edit the CSS as described above and then add this:

#timelineTime, #timelineTimeVertContainer, #timelineContainer, #timelineContainerVert {
        display: none !important;
You can also change the color and font size of the current time by modifying the attributes for those CSS elements like this:

#timelineTime {
	color: green !important;
	font-size: 1.2em !important;
	top: -14px !important;
#timelineContainer {
	border-top-color: green !important;

How can I remove the start time from displaying?

If you don't want to see the event start time until you click on an event, add this to your CSS:

.fc-event-time {
	display: none; 
To pull this from just the Schedule view, preface it with the view name like this:
.fc-view-agendaResourceVert .fc-event-time {
	display: none;
If you'd like to pull the event title alongside the start and end times on the schedule views, try this:
.fc-event-time { 	
	display: inline;  
.fc-event-title { 	
	display: inline;  

How can I show both the start and end date/time for Salesforce sources?

If you'd like to display both the start and end dates or times for Salesforce sources, you can get creative with the Display field mapping value and CSS. This will automatically display the dates for all-day events, and times for events with times.

First, add this to the beginning of the "Display" value for each of your calendar sources to add the start/end values in the normal event time syle while creating a new "display-time-header" class:
<span class="fc-event-time display-time-header"><span>StartDateTime</span> - <span>EndDateTime</span></span>

Next, let's hide the default time display only when not used in the new "display-time-header" class:

 display: none; 
That's it!
If you only want to hide the default time display only for specific sources, take a look at the source-specific instructions here.
Can I prevent the new event popover or plus button from showing?
Yes, add this CSS somewhere after the first few declarations to hide the new event popover:
div[content=newEvent] { 	
	display: none;  
And add this to hide the draggable, green plus button for creating events (the second class moves the analytics button down to where the green plus used to be):
.add-event-container {
	display: none;
.measure-button-container {      
      bottom: 30px !important;

Can I remove the analytics button?

Yes, add this CSS:
.measure-button-container {
  display: none !important;  

Can I remove the delete button from the event's popover?

Yes, add this CSS:
.dbk_editEvent .dbk_button_text_danger {
	display: none;  

Can I remove the custom actions button/cog from the event's popover?

Sure; try this...
dbk_popover .fa-cog {
	display: none;  

That little handle for resizing an event makes small events look too crowded; can I get rid of that?

Yes, this CSS will pull the handle but still let you drag the event:
.fc .ui-resizable-handle {
	opacity: 0; 

Can we change the color/opacity of the new event highlight?

Yes, add this CSS to change the color to yellow and increase opacity/visibility:
	background-color: yellow;
	opacity: .5;
Note: You can specify a color or enter an rgb attribute if desired. Opacity can be specified between 0 (invisible) and 1 (solid).
Can we rotate the column headers on the Resources / Schedule view?
Yes. This a cool little mod =) Note that you have to set your abbreviations to be the same as your resource names to get the full effect. Here's a screenshot, CSS follows:
.fc-view-agendaResourceVert .dbk_columnHeader .fc-widget-header span {
	-webkit-transform: rotate(-70deg);
	-moz-transform: rotate(-70deg);
	-o-transform: rotate(-70deg);
	width: 100px;
	margin-top: -50px;
	top: 190px;
	position: fixed;
	margin-left: -1.2%;
.fc-view-agendaResourceVert .dbk_columnHeader .fc-widget-header {
	text-align: left;
.fc-view-agendaResourceVert .fc-date-header span {
	position: fixed;
  	margin-top: -90px;
.fc-view-agendaResourceVert {
	top: 90px;
.fc-view-agendaResourceVert .dbk_columnHeader .fc-last span[style^="width"] {
	margin-left: -1%;
	position: fixed;
	width: 100px !important

Can I color alternate rows on the schedule views?

Yes. Add this to get alternate-row scheduling that makes the calendar look more like a spreadsheet.
.fc-agenda-slots tr:nth-child(even){
background-color: rgba(173, 216, 230, 0.19);
.fc-agenda-slots tr.fc-minor td {
border-color: #9f9f9f transparent transparent;

Can I hide one of the tabs in the sidebar, like "Filters"?

Yes. I'm not sure you'll want to hide the settings tab as without it there is no way to get to the Account Settings section of the calendar, but if you'd already entered your license--and you remember how to undo what follows--maybe that's ok.
Hiding the tabs is easy. Here's the code to hide Filters and Calendars, resizing Settings. 
.dbk_sidebar .filters, .dbk_sidebar .calendars {
	display: none;
.tabButtonContainer button.settings {
	width: 258px;

Can I adjust the width of the sidebar?

Yes, but a few other objects will need to be adjusted. Here's an example of how to shrink the sidebar width to 265px:
/* Set sidebar width to 265px*/
#sidebar {
  width: 265px;

#header, .message-dialog, .calendar, .sidebar-toggle-container{
  Left: 265px;

.calendar-info .calendar-footer, .calendar-footer-settings{
  Left: -48px !important;

/* Fix search bar in filters menu */
.search-wrapper .fa-search {
  margin-left: 5px;
.search-wrapper textarea {
  width: 150px;

/* Changes the width of the Sidebar tab buttons */
.sidebar .tabButtonContainer .calendars {
    width: 110px !important;

.sidebar .tabButtonContainer .filters, .sidebar .tabButtonContainer .mini-calendars, .sidebar .tabButtonContainer .settings {
    width: 55px !important;

How do I remove the green plus button and the ability to make new events?

There is a just a bit of CSS to add to remove the green plus button in the lower right of the calendar and the "new event" button that shows when you click in an empty calendar cell:
.add-event-button, .dbk_newEvent .btn-success, .add-event-cancel {
	display: none;

Can we change the color of the lines between days of the month or week?

Yes; you can change the grid lines like this:
.fc-widget-content, .fc-widget-content {
	border-color: #a94442;

Can I make the button to show or hide the sidebar more obvious?

Yes; the code below will move this button to the right of the date header, make it larger, and cause the "show sidebar" text to be visible all the time. The last two sections swap out the icon: you can use almost any of the font awesome icons shown  here.
@media only screen
and (min-device-width : 1025px)
and (max-device-width : 3224px) {
	.sidebar-toggle-container {
		margin-left: 400px;
		margin-top: 15px;
	.sidebar-toggle-container .fa-caret-left, .sidebar-toggle-container .fa-caret-right {
		font-size: 40px ;
		color: rgb(66, 139, 202);
	.sidebar-toggle {
		overflow: visible ;
		background-color: #FFFFFF ;
	.sidebar-toggle-label {
		font-size: 13px;
	.sidebar-toggle-container .fa-caret-left:before { 
		content: "\f190" !important;
	.sidebar-toggle-container .fa-caret-right:before { 
		content: "\f18e" !important;

Can I change the icons used throughout the calendar?

Sure! For example, you can change the house icon in DayBack's sidebar to a calendar icon. Change the home icon placeholder, ".dbk_icon_home {}", to this:
.dbk_icon_home::before {
	content: "\f073";
At this  link, you'll find a list of icons that can be used in DayBack. Once you find an icon you'd like to use, follow the form above with any of the icon placeholders to change the corresponding icon. Here are the icon placeholders at use in DayBack:
.dbk_icon_home {}
.dbk_icon_angle_left {}
.dbk_icon_angle_right {}
.dbk_icon_cog {}
.dbk_icon_check {}
.dbk_icon_arrow_left {}
.dbk_icon_arrow_right {}
.dbk_icon_chevron_circle_right {}
.dbk_icon_chevron_circle_left {}
.dbk_icon_help {}
.dbk_icon_add {}
.dbk_icon_cog {}

Note: Watch out for smart quotes! Make sure the icon code is wrapped in straight quotes. Copy/paste these "quotes" if your keyboard just doesn't want to type them in.  

Can I make customizations to a specific view only?

CSS modifications to the calendar can be formatted to only apply to a specific view. If you'd like your changes only to apply when in the mobile (phone) calendar mode, you can use the following selector:


The inverse of that, for when viewing the calendar in the full, non-mobile version is:


Adding one of the following selectors to the beginning of your CSS will specify which view to apply the CSS to:

Name of CSS selector -- Corresponding tab in the calendar
.fc-view-agendaDay -- Day view with times down the left side
.fc-view-basicDay -- Simple Day View
.fc-view-agendaWeek -- Week view with times down the left side
.fc-view-basicWeek -- Simple Week View
.fc-view-month -- month view
.fc-view-basicHorizon -- Gantt Chart
.fc-view-basicResourceDays -- Resource daily view
.fc-view-agendaResourceVert -- Resource tab with times down left side
.fc-view-agendaResourceHor -- Pivot Schedule (was "Grid" view)
.fc-view-basicResourceVert -- Resource tab, list view
.fc-view-basicResourceHor -- Pivot List

You can see an example of CSS applied specifically to the Horizon view in the following section.

What about changing the popover for just one source/calendar?

You can restrict your CSS mods to just one calendar as well. DayBack uses the calendar name as the class name for the popover (use the case sensitive calendar name with spaces and the "@" sign removed). For example, this will hide the custom actions cog on just the calendar named "Sample Events":
.SampleEvents .dbk_popover .fa-cog {
	display: none;

`The calendar name is also used as a class in this way when drawing an event the calendar (such as how the event appears on the month view before you click on it). For example, this will give events for the Sample Events source a drop shadow:

fc-event.SampleEvents {
	border-color: rgba(0, 0, 0, .3);
	border-width: 1px;
	-webkit-box-shadow: 3px 10px 11px 0px rgba(0, 0, 0, 0.75);
	-moz-box-shadow: 3px 10px 11px 0px rgba(0, 0, 0, 0.75);
	box-shadow: 3px 10px 11px 0px rgba(0, 0, 0, 0.75);

I'd like to shade weekends in Horizon view so it's easier to see where weeks start and stop?

Great idea:
.fc-view-basicHorizon .dbk_day_sat .fc-day-content, .fc-view-basicHorizon .dbk_day_sun .fc-day-content {
	background-color: rgba(200, 201, 204, 0.11) !important;

You might also like this mod, which adds a vertical line to the beginning of your week. Works great with the mod above. In your CSS, replace "mon" with your start day.

.fc-view-basicHorizon .fc-mon {
	border-color: rgba(10, 189, 237, 0.22) !important;
	border-left-width: 2px;
Here is a before and after of what these two mods look like; it's subtle but I think it makes the horizon view easier to scan at a glance:

Can I change the color of the "none" resource column?

Yes! Using this technique you can assign a color to any resource column simply by replacing "none" with the name of that resource.

.dbk_calendarContent td[data-resource="none"] {
	background-color: #DFECF5 !important;	

Can I style the date numbers in the sidebar's mini-calendar?

Sure thing. The .dbk_dayNumber selector will let you style all day numbers in the mini-calendar. Or, you can target just the current day or selected day (date in focus). For example, you might want to make the current day and the selected day bold:
.dbk_dayNumber.dbk_today, .dbk_dayNumber.dbk_selected {
	font-weight: bold;

How can we remove the "New Status" button in the filters sidebar?

While you can't pull this for only some users, you can remove it entirely. (Remember that these buttons to add statuses and resources only show for DayBack administrators, and you can decide who those are). Here is the CSS for removing the button outright:
.list-selector.list-event-button {
	display: none;
If you want to pull the "cog" icon for adjusting status names and colors you can use this:
.list-selector .fa-cog {
	display: none !important;

I'd like to hide the help icons that link to DayBack's docs

No problem. Just add this to your CSS:
button.btn.btn-link.btn-help {
	display: none;

Can I change the appearance of collapsed 'breakout' rows in Horizon view?

Sure. Here is the CSS for the screenshot below:
.breakout-title-collapsed td {
	color: rgb(183, 184, 190);
	background-color: rgb(250, 250, 250);

Can I change the size of the label column in the Resource Pivot views?

Sure. Adjust the width value in the following CSS to adjust the column size:

Can I change the “Selecting contacts is only available in Salesforce” message?

Yes. Add this to remove the default message and add your own:
contact-selector div:first-child:before {
	content: "Selecting contacts coming soon.";
contact-selector .pad div:first-child {
	display: none;
project-selector div:first-child:before {
	content: "Selecting projects coming soon.";
project-selector .pad div:first-child {
	display: none;

Can I make a specific popover field read-only?

While we don't yet have a built-in way of making specific fields read-only, you can prevent users from being able to click on a specific field using the following attribute:
pointer-events: none;
For example, preventing users from clicking into the Title field (and making it darker than other fields) can be done with:
.dbk_editEvent #title{
	pointer-events: none;
	background: rgb(204, 204, 204);
	color: rgb(51, 51, 51);
	border-color: rgb(60,60,60)
Note: Since this only prevents mouse clicks, it works great for picklist items, like Resource, or Status, but users will still be able to use the Tab button to enter a text field.

Can I increase the default heights of text fields in the popover?

Sure thing. The different fields are listed below with their default heights.
/*Title height*/
textarea.title-input { 

	min-height: 34px; 

/*Description height*/
	textarea#description { 

min-height: 78px; 

/*Additional Fields height -- affects all text "edit" additional fields*/
	.utility-panel textarea {

min-height: 28px; 

Increasing the height of title and/or description may cause a scroll bar to appear in the popover for overflow. If you'd like to avoid that popover scroll bar, you can increase the height of the whole popover as well. Be sure to adjust these two values by the same amount (although that amount may not exactly correlate to the adjustments made above).
.edit {

height: 460px; 


.edit .field-container { 

max-height: 375px;


Can I color the background of specific dates like holidays?

Yes, though you may want to consider creating appointments (or availability appointments) for holidays instead: appointments will show up on every calendar view (the CSS below only works on Month and Horizon view) and appointments can be created using DayBack's repeating events engine. But if you do want to style a specific date, here's how.
[data-date="2018-07-23"] {

Can I add a colored frame around some events?

Yes, you'll find instructions and CSS for this here: Color-Coding by Resource.

How can I find the class names in DayBack?

You can use the online version of DayBack to inspect the classes available to you. Here's a cool little video to show you how.
