Design basic UI¶¶

The minimal definition of User Interface(UI) represents look, feel and interactivity of the website. It includes thinking properly about icons and buttons, typography and color schemes, spacing, image placement, responsive design etc.

In our IdeaStore app context, we have to design the UI of two pages:

• List of ideas (/ideas/)
• Display of one idea (/ideas/1)

application.css¶¶

If you want to use CSS for styling the web pages in your application, you need to add all your CSS inside app/stylesheets/application.css file.

UI design for ideas list¶¶

Add following CSS inside app/stylesheets/application.css:

html {
  font-family: arial, sans-serif;
}

table {
  border-collapse: collapse;
}
td, th {
  border: 1px solid #ddd;
  text-align: left;
  padding: 10px;
}
tr:nth-child(even) {
  background-color: #eee;
}

The idea listing page should look as follows:

UI design for single idea¶¶

First update the show.html.erb as follows:

<h1>Idea</h1>

<div class="idea">
  <div class="title">
    <strong>Title: </strong> <%= @idea.title %>
  </div>
  <div class="description">
    <strong>Description: </strong>
    <p>
      <%= @idea.description %>
    <p>
  </div>
</div>

Then, add following css for styling single idea into application.css:

.idea {
  border: 1px solid #ddd;
  width: 350px;
}
.idea .title {
  background-color: #eee;
  padding: 10px;
}
.idea .description {
  padding: 10px;
  height: 100px;
}

The idea page should look as follows:
