CSS/SASS Styles

Load the default Bootstrap theme style and/or customize it to your taste (customization can applied by using SASS)

CSS

Default compiled css (if you use the plain Bootstrap Theme CSS, you could simply add it to your .angular-cli.json file and be done with it)

"styles": [
    "../node_modules/bootstrap/dist/css/bootstrap.css",
    "../node_modules/font-awesome/css/font-awesome.css",
    "../node_modules/flatpickr/dist/flatpickr.css",
    "../node_modules/angular-slickgrid/lib/multiple-select/multiple-select.css",
    "styles.css",
    "../node_modules/angular-slickgrid/styles/css/slickgrid-theme-bootstrap.css"
],

SASS (.scss)

You could also compile the SASS files with your own customization, for that simply take any of the _variables.scss (without the !default flag) variable file and make sure to import the Bootstrap Theme afterward. For example, you could modify your style.scss with the following changes:

/* for example, let's change the mouse hover color */
$slick-cell-odd-background-color: lightyellow;
$slick-row-mouse-hover-color: lightgreen;

/* make sure to add the @import the SlickGrid Bootstrap Theme AFTER the variables changes */
@import '../node_modules/angular-slickgrid/styles/sass/slickgrid-theme-bootstrap.scss';

Using CSS Variables (instead of SASS)

You could change the SlickGrid styling with your own customization using CSS Variables. The variables that you can use (over 800 of them) are all predefined as SASS variables in the _variables.scss file, you will simply have to rename the $slick- prefix with a --slick- prefix to the variable name to use them as CSS Variables. To be clear, you don't need SASS but the variables names were all declared as SASS and that is what the lib will use internally but you can optionally use them all as plain CSS Variables.

For example, if we take the following 3 SASS variables ($slick-header-menu-display, $slick-primary-color-dark and $slick-header-filter-row-border-bottom) we can use the CSS Variables equivalent as the following

/* use :host (local) or :root (global) */
:root {
    --slick-header-menu-display: inline-block;
    --slick-primary-color-dark: pink;
    --slick-header-filter-row-border-bottom: 2px solid pink;
}

NOTE: you could use :host to only change current grid styling, however there are many DOM elements that are appended to the Document body (Grid Menu, Column Picker, Select Filter/Editor, Context Menu, ...) and the style will not be applied with :host and so in most cases you would want to use :root to make a global change which will also work with elements appended to the body.

Bootstrap support

The creation of Angular-Slickgrid started with Bootstrap 3 and now it's up to Bootstrap 5 as the Bootstrap library keeps evolving.

• Bootstrap 4 demo / examples repo
• Bootstrap 5 demo / examples repo

Other UI frameworks

Note that Bootstrap is totally optional, you could use any other UI framework, also 2 new themes were added in version 2.18.x, first is a Material Design Theme and also a Salesforce Theme.

• Material Theme - demo
• Salesforce Theme - demo

For more demo, you can also take a look at my other repo (Slickgrid-Universal) demos. Also, note that Bootstrap is completely optional (and has been for some time), the other demo that I mentioned was created using only the Bulma CSS framework, you will also notice that only the Material & Salesforce Themes were used across these multiple examples.

Each of these Styling Themes are compiled in CSS and created from a SASS file, so you can use either or. Both Themes are shown in each Tree Data demo

• Note: you might need to refresh the page to see the theme correctly since the styling is global and if you change page, the style will follow on the next page (unless you refresh).

SVG Icons

The 2 new Themes were created with only SVG icons, most of the icons were pulled from the Material Design Icons set. If you wish to create your own set of SVG Icons, you can refer to the new Wiki - SVG Icons

• Wiki - SVG Icons.

Note: Just to point out that both the Fonts and SVG icons are supported, the default Bootstrap theme will keep Font-Awesome 4 so that it still works for everyone. You could however use SASS to override the Font and use SVG, again see the Wiki - SVG Icons for more details.
