+title: Customising Admonitions
+description: A comprehensive guide on how to easily edit admonitions and their appearance.
+---
+
+:::success[Beginner Friendly]
+
+This guide is made for beginners, by beginners, aiming to explain how Docusaurus uses HTML
+and CSS to create page elements. No prior front-end knowledge is needed!
+
+:::
+
+When working on your Docusaurus project, you may not like the appearance of the default
+admonitions... If you are looking to override their color WITHOUT creating a whole new
+admonition, then you've come to the right place!
+
+:::info
+
+This page does not cover how to create custom admonitions, only overriding the default
+Docusaurus admonition appearance. If you want to create custom admonitions that DON'T interfere with the default
+admonitions, we have a guide for that: [Admonitions](/knowledge/component-library/existing/Admonitions/)
+
+:::
+
+## Background Knowledge
+
+If you are unfamiliar with the Docusaurus admonitions and their appearance, visit the Docusaurus
+official documentation relating to admonitions by clicking the button below.
+
+<DocusaurusButton
+  label="Docusaurus Documentation: Admonitions"
+  to="https://docusaurus.io/docs/markdown-features/admonitions"
+/>
+
+To understand how admonitions work, we need to utilize Inspect Element to find things such
+as HTML class names and CSS values that the admonitions use.
+
+### Using Inspect Element
+
+The best way to see how admonitions work (if you are using Chrome) is to highlight the title
+of the admonition, right-click, and select "Inspect." This will bring up Inspect Element.
+Inspect is key to figuring out how to override the appearance of the default admonitions.
+
+:::tip
+
+If you want to make changes to any element of your website but find yourself stuck, Inspect
+Element is a powerful tool for making local, temporary changes!
+
+:::
+
+![Use Inspect on the "note" admonition's title](inspect-admonition.png)
+
+From here, we can find the HTML of all the Docusaurus page elements. For this guide, we are only
+going to focus on the admonitions.
+
+## Analyzing the HTML (Using Inspect)
+
+When clicking inspect on your site, you may find something like this:
+
+![Inspect Element of a Docusaurus website](inspect-element.png)
+
+Don't be afraid! This is the HTML that Docusaurus generates to make your website!
+If you click around in Inspect Element, you will eventually find the elements that
+are the admonitions. We can see that the "note" admonition that we highlighted is
+an HTML `<div>` element, with a couple of classes attatched to it.
+
+![The "note" admonition's HTML code](note-admonition-html.png)
+
+For our purposes, we are interested in that last class: `alert--secondary`. This is
+the driving class that tells the "note" admonition what colors to use. We can find what
+variables it uses with Inspect Element as well. Switch to the "Styles" tab in Inspect Element
+and use the search bar to find the "note" admonition's class: `alert--secondary`.
+
+## Analyzing the CSS (Using Inspect)
+
+![The "note" admonition's CSS code](note-css.png)
+
+This is the note admonitions CSS code. This is what tells the note admonition what
+colors to use. We see four attributes and their corresponding default variables:
+
+### ⭐️ Note admonition's default CSS Values
+
+| CSS Attribute                            | Default Value                                    |
+| ---------------------------------------- | ------------------------------------------------ |
+| `--ifm-alert-background-color`           | `var(--ifm-color-secondary-contrast-background)` |
+| `--ifm-alert-background-color-highlight` | `rgba(235, 237, 240, 0.15)`                      |
+| `--ifm-alert-foreground-color`           | `var(--ifm-color-secondary-contrast-foreground)` |
+| `--ifm-alert-border-color`               | `var(--ifm-color-secondary-dark)`                |
+
+![Diagram that points to what each admonition variable corresponds to on an example "note" admonition](admonition-var-diagram.png)
+
+Let's say we want to override the background of the "note" admonition to purple. Well,
+we can change the value using Inspect and see the color update in real time. Try changing
+the value of `--ifm-alert-background-color` to any color!
+
+:::warning
+
+All changes made using Inspect Element are temporary! Refreshing the page will revert any changes
+we made with Inspect.
+

+
+## Updating the CSS
+
+Now that we know that the CSS is responsible for the appearance of admonitions, we need to
+update the CSS code of our Docusaurus site to override the default values to our new colors.
+
+In your code editor, in the directory of your Docusaurus site, navigate to `src/css/custom.css`.
+This is where we can add permanent overrides to the CSS of our site, which means we can update the
+colors of our admonitions.
+
+We want to make overrides to the `alert--secondary` (note admonition) class's CSS we found. Add the
+`alert--secondary` class to your `custom.css` by copy and pasting the code below into `custom.css`.
+
+```css title="src/css/custom.css"
+.alert--secondary {
+  --ifm-alert-background-color: rgb(237, 219, 255);
+  --ifm-alert-background-color-highlight: rgb(235, 237, 240);
+  --ifm-alert-foreground-color: var(--ifm-color-secondary-contrast-foreground);
+  --ifm-alert-border-color: var(--ifm-color-secondary-dark);
+}
+```
+
+Now, we can change the variables here to any color we desire! This next code block will override the
+"note" admonition's color to an example of colors.
+
+```css title="src/css/custom.css"
+.alert--secondary {
+  --ifm-alert-background-color: rgb(210, 216, 255);
+  --ifm-alert-background-color-highlight: rgb(233, 187, 255);
+  --ifm-alert-foreground-color: rgb(216, 36, 111);
+  --ifm-alert-border-color: rgb(38, 31, 41);
+}
+```
+
+![The "note" admontion with custom colors](note-custom-colors.png)
+
+:::tip
+
+You can also define colors using hex values!
+
+```css title="src/css/custom.css"
+.alert--secondary {
+  --ifm-alert-background-color: #d2d8ff;
+  --ifm-alert-background-color-highlight: #e9bbff;
+  --ifm-alert-foreground-color: #d8246f;
+  --ifm-alert-border-color: #261f29;
+}
+```
+
+:::
+
+## ⭐️ Admonition Class Names
+
+Here are the names of all the default admonition classes:
+
+| Admonition | Class Name         |
+| ---------- | ------------------ |
+| Note       | `alert--secondary` |
+| Tip        | `alert--success`   |
+| Info       | `alert--info`      |
+| Warning    | `alert--warning`   |
+| Danger     | `alert--danger`    |
+
+You can use these class names in `custom.css` to override their appearance as well, just
+like how we did with the "note" admonition.
+
+## Making Color-Responsive Admonitions
+
+You may notice that your new colors might not look good when your Docusaurus site switches
+from light mode to dark mode (or vice versa). In order to make our admonitions responsive
+to the color mode of our website, we can use custom CSS variables!
+
+### Make a Custom CSS Variable
+
+First, let's make a custom CSS variable that will store any color of our choice.
+
+In your `custom.css`, Docusaurus comes with a `:root` and a `[data-theme='dark']` config by
+default. You can name your variable anything you would like, just make sure it is descriptive
+and fits your needs!
+
+:::note
+
+It is recommended you add a new config: `[data-theme='light']`, although, it is not
+required, and all light mode variables can be put inside of `:root`. The guide will continue with
+creating the new config for the light theme.
+
+:::
+
+```css css title="src/css/custom.css"
+[data-theme='light'] {
+  --note-bg: rgb(210, 216, 255);
+}
+```
+
+### Apply Custom CSS Variable
+
+Now that we created our new color variable `--note-bg`, we have to apply it to the `alert--secondary`
+CSS class. Update the static RGB value of `.alert--secondary` to our new variable, using `var()`.
+
+```css title="src/css/custom.css"
+.alert--secondary {
+  // highlight-next-line
+  --ifm-alert-background-color: var(--note-bg);
+  --ifm-alert-background-color-highlight: rgb(233, 187, 255);
+  --ifm-alert-foreground-color: rgb(216, 36, 111);
+  --ifm-alert-border-color: rgb(38, 31, 41);
+}
+```
+
+Now, let's add a color for when the page is in dark mode. The procedure is very similar to the
+previous steps, excpt we are adding a new variable to the dark mode config!
+
+```css title="src/css/custom.css"
+[data-theme='light'] {
+  --note-bg: rgb(210, 216, 255);
+}
+
+[data-theme='dark'] {
+  --note-bg: rgb(83, 73, 126);
+  // ...
+}
+```
+
+Let's go ahead and set the colors of all our other parts of the note admonition. Here's an
+example:
+
+```css title="src/css/custom.css"
+[data-theme='light'] {
+  --note-bg: rgb(210, 216, 255);
+  --note-highlight: rgb(233, 187, 255);
+  --note-foreground: rgb(216, 36, 111);
+  --note-border: rgb(38, 31, 41);
+}
+
+[data-theme='dark'] {
+  --note-bg: rgb(83, 73, 126);
+  --note-highlight: rgb(68, 58, 72);
+  --note-foreground: rgb(255, 255, 255);
+  --note-border: rgb(226, 158, 255);
+  // ...
+}
+
+.alert--secondary {
+  --ifm-alert-background-color: var(--note-bg);
+  --ifm-alert-background-color-highlight: var(--note-highlight);
+  --ifm-alert-foreground-color: var(--note-foreground);
+  --ifm-alert-border-color: var(--note-border);
+}
+```
+
+### Results
+
+Now we can observe that the colors of our "note" admonition change between light mode and dark
+mode!
+
+![Light mode "note" admonition with custom colors](light-mode-note.png)
+
+![Dark mode "note" admonition with custom colors](dark-mode-note.png)
+
+## Conclusion
+
+Congratulations! You are now a pro at overriding the basic colors of the "note" admonition!
+Using your knowledge, you should be able to override the colors of all the default admonitions using
+the [class names](#%EF%B8%8F-admonition-class-names) listed above!
+
+:::tip
+
+Use your new HTML and CSS knowledge to see what other elements of the webpage you can edit! Find
+their class names, and tinker with them in your `custom.css` file, just like how you did with the
+"note" admonition!
