Customize Your DataHub Cloud Site with CSS

Introduction

In this tutorial, we're going to explore how you can personalise the appearance of your DataHub Cloud site. By the end of this tutorial, you'll learn how to use a custom.css file to adjust existing styles and how to add and style a simple hero to your landing page.

What You'll Need

• GitHub account and basic knowledge of GitHub UI (especially editing and adding files)
• A DataHub Cloud site you want to customise.
• Basic knowledge of CSS (or more, depending on what you want to achieve)
• Basic knowledge of browser developer tools.

Part 1: Adjusting Default Styles with custom.css

Here is an example landing page of a site published with DataHub Cloud that we're going to style. You can use any of your DataHub Cloud sites.

Here is the underlying markdown content:

---
title: My Musings & Memories 🧘‍♀️🏄‍♀️🏔️
description: "Welcome to my personal corner of the web, where I'll be sharing my thoughts, travel experiences, coding projects, and much more!"
date: 2024-04-24

Step 1: Create the custom.css File

In the root of your site's GitHub repository, create a file named custom.css.

Step 2: Change Background Colour & Heading Fonts

Now, let's change the background colour and heading fonts a bit.

Add the following CSS rules in your custom.css file and commit your changes. Then, go to your DataHub Cloud dashboard and sync your site.

/* Change heading fonts and colors */
.bg-background {
    background: #f9f6f1 !important;
}

h1, h2, h3, h4, h5, h6 {
    font-family: "Lucida Console", "Courier New", monospace !important;
    font-weight: bold !important;
}

h1, h4 {
    color: #d30c7b !important;
}

h2, h5 {
    color: #ba5a31 !important;
}

h3, h6 {
    color: #508484 !important;
}

Here is the end result on our example page. Pretty nice, huh?

Step 3: Style Anything You Want

This was just a basic example of tweaking css on your DataHub Cloud site. But you can style virtually anything you can see on your page. You just need to find out how to properly "select" the HTML element you want to style in your custom.css.

Part 2: Adding a Simple HTML Hero

Did you know that you can include HTML tags in your markdown? If not, let me show you how. Then, you'll be able to use the knowledge from Part 1 and style those elements too!

Let's try replacing the current header (title, description, and date) in our example with a simple hero element.

Step 1: Add a Simple HTML Hero

Let's replace the current frontmatter with the following HTML snippet:

<div class="hero">
    <h1 class="hero-title">My Musings & Memories<br/>🧘‍♀️🏄‍♀️🏔️</h1>
    <p class="hero-description">Welcome to my personal corner of the web, where I'll be sharing my thoughts, travel experiences, coding projects, and much more!</p>
    <a href="/blog" class="hero-button">See my blog</a>
</div>

The markdown file now looks like this:

<div class="hero">
    <h1 class="hero-title">My Musings & Memories 🧘‍♀️🏄‍♀️🏔️</h1>
    <p class="hero-description">Welcome to my personal corner of the web, where I'll be sharing my thoughts, travel experiences, coding projects, and much more!</p>
    <a href="/blog" class="hero-button">See my blog</a>
</div>

Now, commit your changes.

Step 2: Style Your Hero with custom.css

Back in your custom.css file, add the following styles (or other!) for your custom hero section:

...

.hero {
  background-color: #508484;
  height: 500px;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  text-align: center;
  color: #fff;
  padding: 0 36px;
}

.hero-title {
  font-size: 4rem;
    color: #E35AA6 !important;
    margin-bottom: 0px;
}

.hero-description {
  font-size: 1.5rem;
  margin-bottom: 30px;
}

.hero-button {
  background-color: #fff;
  color: #333;
  padding: 10px 20px;
  border-radius: 5px;
  text-decoration: none;
  font-weight: bold;
  transition: all 0.3s ease-in-out;
}

.hero-button:hover {
  background-color: #D679AC;
  color: #fff;
}

Once again, commit your changes. Now, head to your DataHub Cloud dashboard and sync your site. Now you can refresh your browser and you should see your landing page with the styled hero. Our example looks like this:

You can also add this extra hack to make the hero break out of the parent container and span the whole site width:

.hero {
  ...
  margin: 0 calc(min(28rem - 1.5rem - 50vw, 0px));
  margin-top: -3rem;
}
