Implementing the Android Logo with HTML and CSS

#html #css #android

In this article, We will implement the android logo with just HTML and CSS. This may seem like a ton of work but we will go through it step by step. I will try to explain as much as I can.

I will share a link to the codebase on Github at the end of this article.

Let us start by creating a simple html file called index.html, that contains this code.

<!DOCTYPE html>
  <html lang="en">

  <head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Android Logo</title>
  </head>

  <body>
    <div class="android">
        <div class="head">
          <div class="left_antenna"></div>
          <div class="right_antenna"></div>
          <div class="left_eye"></div>
          <div class="right_eye"></div>
        </div>
        <div class="body">
          <div class="left_arm"></div>
          <div class="right_arm"></div>
          <div class="left_leg"></div>
          <div class="right_leg"></div>
        </div>
    </div>
  </body>

</html>

This markup is pretty self explanatory. It seems weird that the legs are in the body section, but don't worry you will understand the concept as we progress.

Next up: Create an index.css file and link it to your index.html file.

<link rel="stylesheet" href="index.css">

At this point nothing is displayed on the user interface as the markup elements have no contents.

Let us start by centre aligning the android vertically and horizontally. We will achieve this by using flex box.
Do:

Give the body of the document a height of 100vh. This sets the height of the body to the height of current device from which the page is being viewed. The height property is also needed to align the logo vertically.
Set display property of the body of the document to flex. This property sets the flexible length on flexible items. This enables us to set other flex properties .
Set justify-content property of the body to center. On default some html elements take up 100% of the width of their parent element. This property sets the position of the element along that horizontal axis.
Set align-items property of the body to center. With the height set, this positions all children element to the center of the view vertically.
Set the position of all divs in a div to relative and set its background to #A4CA39

At this point your index.css file should look like this

body {
    align-items: center;
    display: flex;
    height: 100vh;
    justify-content: center;
}

div div {
    background: #a4ca39;
    position: relative;
}

We have our layout all set, if you try to access this in your browser you will not see anything just a white space. Without further ado, let us dive into the android styling

We will start by styling the android itself
Do:

Set the width and height of android class (.android) to 340px and 400px respectively.

Then we will style the head of our android logo
Do:

Set the width and height of the head class (.head) to 200px and 100px respectively.
Set the top property to 32px to make space for the antennas.
In order to achieve the semi-circular shape of the android's head, we will set the border-radius property to 220px 220px 0 0. This sets the border-radius of the top-left, top-right, bottom-right and bottom-left of the head respectively. We used a short hand property here, we could as well use border-top-left-radius, border-top-right-radius and so on.

At this point we should have a somewhat semi-circular head of our android logo popping out like this

Waiting for the css code? No sorry I won't give it to you just yet. Try to follow along and see how much of this you can get correctly, it will make your learning experience better.

Let us proceed

Next up is the eyes and antennas of our android

Eyes

For the similarities, do:

Set the background color of both eyes to white.
Set the width and height to 20px.
Set the position property to absolute, so that we can move it to the position that we want to.
Set the top property to 42px.
and the border-radius to a 100%.

For the differences, do:

Set the left eye's left property to 50px.
Set the right eye's right property to 50px.

Antennas

For the similarities, do:

Set the width and height to 6px and 50px.
Set the position property to absolute, so that we can move it to the position that we want to.
Set the top property to -34px.
and the border-radius to a 3px.

For the differences, do:

Set the left antenna's left property to 50px and rotate it for a degree of -30
Set the right antenna's right property to 50px and rotate it for a degree of 30

At this point we should have the head of our android logo looking like this

Next up is the body

This is actually the simpler part as it is just a rectangle and we get to manipulate the border-radius property in a similar fashion as we did for the head.
For the body of the android logo, do:

Set the width and height to 200px and 184px respectively.
Set the top property to 42px.
Set the border-radius to 0 0 25px 25px.

At this point we should have the head of our android logo looking like this

Yeah yeah, let out that wide smile.

Next up is the arms and legs

The Arms and Legs have some similarities, to see them do:

Set the width to the both arms and legs to 50px.
Set the position to absolute.

For the similarities of the arms, do:

Set the height to 150px.
Set the border-radius to 25px.

Differences between the two arms is that they should be pulled away from the body for 58px on both sides.

For the similarities of the legs, do:

Set the height to 100px, since the legs on the logo are shorter than the arms.
Set the border-radius to 0 0 25px 25px.
Set the top property to 192px. This will pull the legs just below the body and also adding a little space between them.

Differences between the two legs is that they should be pulled into from the body for 40px on both sides.

HOOALA behold our android logo

At this point your index.css should look like this:

body {
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

div div {
  background: #A4CA39;
  position: relative;
}

.android {
  height: 400px;
  width: 340px;
}

.head {
  width: 200px;
  height: 100px;
  top: 32px;
  border-radius: 220px 220px 0 0;
}

.left_eye,
.right_eye {
  background: #fff;
  width: 20px;
  height: 20px;
  position: absolute;
  top: 42px;
  border-radius: 100%;
}

.left_eye {
  left: 50px;
}

.right_eye {
  right: 50px;
}

.left_antenna,
.right_antenna {
  width: 6px;
  height: 50px;
  position: absolute;
  top: -34px;
  border-radius: 3px;
}

.left_antenna {
  left: 50px;
  transform: rotate(-30deg);
}

.right_antenna {
  right: 50px;
  transform: rotate(30deg);
}

.body {
  width: 200px;
  height: 184px;
  top: 42px;
  border-radius: 0 0 25px 25px;
}


.left_arm,
.right_arm,
.left_leg,
.right_leg {
  width: 50px;
  position: absolute;
}

.left_arm,
.right_arm {
  height: 150px;
  border-radius: 25px;
}

.left_leg,
.right_leg {
  height: 100px;
  top: 192px;
  border-radius: 0 0 25px 25px;
}

.left_arm {
  left: -58px;
}

.right_arm {
  right: -58px;
}

.left_leg {
  left: 40px;
}

.right_leg {
  right: 40px;
}

Yes you are right @neilonsoftware , this is for the purpose of a learning exercise. And an SVG would be preferred in a real world application. Here the reader gets to learn about some concepts and what they do like positioning etc. This knowledge they can apply in other aspects of real world problems.

hi,
just finished it. was great. thank you.
2 things:
1 - the arms are 58px away (50 + 8) - i saw 50 and it drove me crazy...
2 - the .android is centered - as it should be, but the inside is not. if you inspect, you'll see it's all aligned left. how can that be fixed?
also - there's a default margin by the browser and it ads a scroll to the side.
again - was great. thank you.
