5: Styles

5.1: CSS

Our user interface up until this point has looked quite ugly. Let’s add some basic styling which will serve as the foundation for a more professional looking app.

Replace the content of our client/main.css file with the one below, the idea is to have an app bar in the top, and a scrollable content including:

  • form to add new tasks;
  • list of tasks.

client/main.css

body {
  font-family: sans-serif;
  background-color: #315481;
  background-image: linear-gradient(to bottom, #315481, #918e82 100%);
  background-attachment: fixed;

  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;

  padding: 0;
  margin: 0;

  font-size: 14px;
}

button {
  font-weight: bold;
  font-size: 1em;
  border: none;
  color: white;
  box-shadow: 0 3px 3px rgba(34, 25, 25, 0.4);
  padding: 5px;
  cursor: pointer;
}

button:focus {
  outline: 0;
}

.app {
  display: flex;
  flex-direction: column;
  height: 100vh;
}

.app-header {
  flex-grow: 1;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

.main {
  display: flex;
  flex-direction: column;
  flex-grow: 1;
  overflow: auto;
  background: white;
}

.main::-webkit-scrollbar {
  width: 0;
  height: 0;
  background: inherit;
}

header {
  background: #d2edf4;
  background-image: linear-gradient(to bottom, #d0edf5, #e1e5f0 100%);
  padding: 20px 15px 15px 15px;
  position: relative;
  box-shadow: 0 3px 3px rgba(34, 25, 25, 0.4);
}

.app-bar {
  display: flex;
  justify-content: space-between;
}

.app-bar h1 {
  font-size: 1.5em;
  margin: 0;
  display: inline-block;
  margin-right: 1em;
}

.task-form {
  display: flex;
  margin: 16px;
}

.task-form > input {
  flex-grow: 1;
  box-sizing: border-box;
  padding: 10px 6px;
  background: transparent;
  border: 1px solid #aaa;
  width: 100%;
  font-size: 1em;
  margin-right: 16px;
}

.task-form > input:focus {
  outline: 0;
}

.task-form > button {
  min-width: 100px;
  height: 95%;
  background-color: #315481;
}

.tasks {
  list-style-type: none;
  padding-inline-start: 0;
  padding-left: 16px;
  padding-right: 16px;
  margin-block-start: 0;
  margin-block-end: 0;
}

.tasks > li {
  display: flex;
  padding: 16px;
  border-bottom: #eee solid 1px;
}

.tasks > li > span {
  flex-grow: 1;
}

.tasks > li > button {
  justify-self: flex-end;
  background-color: #ff3046;
}

Flexbox is an excellent tool to distribute and align elements in your UI.

5.2: Applying styles

Now you need to add some elements around your components. You are going to add a className to your main div in the App, also a header element with a few divs around your h1, and a main div around your form and list. Check below how it should be, pay attention to the name of the classes, they need to be the same as in the CSS file:

imports/ui/App.jsx

  ..
  return (
    <div className="app">
      <header>
        <div className="app-bar">
          <div className="app-header">
            <h1>Welcome to Meteor!</h1>
          </div>
        </div>
      </header>

      <div className="main">
        <TaskForm />

        <ul className="tasks">
          {tasks.map(task => (
            <Task
              key={task._id}
              task={task}
              onCheckboxClick={toggleChecked}
              onDeleteClick={deleteTask}
            />
          ))}
        </ul>
      </div>
    </div>
  );

In React we use className instead of class as React uses Javascript to define the UI and class is a reserved word in Javascript.

Also choose a better title for your app, Meteor is amazing but you don’t want to see Welcome to Meteor! in your app top bar all the time.

You could choose something like:

imports/ui/App.jsx

  ..
  <h1>📝️ To Do List</h1>
  ..

Your app should look like this:

In the next step we are going to make this task list more interactive, for example, providing a way to filter tasks.
