poster

Part 1: Link to .CSS file

  1. Open accessories.html and add following element in the head section.

    <link rel="stylesheet" type="text/css" href="style.css">

  2. Open style.css

  3. Create a body selector.

  4. Add background-color property.

    body {
	background-color: black;
}

  5. Check if website color changed.

  6. Use browser developer tools to find out the banner's hex color code.

  7. Change the value of background-color to the Hex code.

Part 2: Contain item in a border

  1. Create a class named container above earring image element.

    <div class = "container">
	<img src = "earrings.jpg" alt = "Diamond Earings">

  2. Close the container below the Order button element.

    		</button>
	</div>
</div>

  3. Open style.css and add container class as a selector, create a 10px border.

  4. Set the width to 285px and padding to 60px and see what happens.

    .container {
	border: 10px solid block;
	width: 285px;
	padding: 60px;
}

Part 3: Centering the container

  1. Remember, to center elements you only need to use display and margin properties.

    display: block;
margin: auto;

  2. Add these two properties into container class.

  3. Refresh the page and the find the container in the middle.

  4. Next step is to center the items inside the container.

  5. Create a selector that selects everything inside container.

    .container * {
	display: block;
	margin: auto;
}

  6. Refresh the page and see the elements inside the container centered.

  7. Notice that the 'Click here' link has became a block element.

  8. To fix that, select 'a' in container and set it to inline.

    .container a {
	display: inline;
}

Part 4: Floating card with shadows

  1. First step, open accessories.html file and locate the table element.

  2. Set the table border to 0.

    <table border = "0" style = "text-align: center;">

  3. Meanwhile, remove the colons ':' from the table labels.

  4. Now go back to style.css.

  5. Locate container class and set the background-color to white.

  6. Add border-radius property with a value of 20px to change the four corners of the card to rounded.

    .container {
	...
	background-color: white;
	border-radius: 20px;
}

  7. Next, remove or comment the border property.

  8. Add a box-shadow property with the following values.

    .container {
	...
	border: 1px solid white;
	box-shadow: 2px 6px 25px rgba(0,0,0,0.1);
}

  9. In RGBA, RGB - Red, Green, Blue. A stands for Alpha. It is used for setting the opacity of the color.

  10. Now we can add some extra padding to the paragraph and image elements to make it look cleaner.

    .container p {
	padding: 30px 8px;
}

img {
	padding-bottom: 40px;
	display: block;
	margin: auto;
}

Part 5: Task - Reuse card in order form

  1. Open orderForm.html and link to style.css.
  2. Copy the same banner(change to max-width:100% in both pages) from accessories.html to show consistency.
  3. Some tips:
    • You don't need to touch the CSS file, just repeat steps 1 & 2 of Part 2.
    • To fix the messy form elements, take a look at step 8 of Part 3.

Part 6: Fixing the button

  1. Let's go back to accessories page.

  2. Take a look at the order button, there is an underline because it is a link.

  3. Also notice that only the link can be clicked, where the rest of the button area is unclickable.

  4. To fix this, go to accessories.html and scroll to the bottom to locate the button element.

  5. The mistake is that the button element is containing the link element.

  6. Change both the elements as below:

    <a href = "orderForm-done.html"><button type = "button">Order</button></a>

  7. To remove the underline, go to style.css and locate .container a that you created in step 8 of Part 3.

  8. Add in a new property called text-decoration and set the value to none.

    .container a {
	...
	text-decoration: none;
}

Part 7: Redesigning the button

  1. Now that the button is fixed, we can start adding some colors to it.

  2. First, add a button selector in style.css.

  3. Add padding with the value of top/bottom: 15px, left/right: 30px.

  4. Set the border-radius to 10px.

    button {
	padding: 15px 30px;
	border-radius: 10px;
}

  5. Next, remove the border and set a background-colorto the button

  6. Add shadows to the button to make it pop out.

    button {
	...
	border: 0px;
	background-color: #FFB0BE;
	box-shadow: 1px 4px 6px rgba(0,0,0,0.1);
}

  7. Change the font color, weight and size.

    button {
	...
	color: white;
	font-weight: bold;
	font-size: 13px;
}

  8. Now, let's add a mouse hover effect on the button.

  9. Create a new button:hover selector.

  10. Copy the box-shadow property from Step 6 and set it wider and darker.

    button:hover {
		box-shadow: 1px 4px 16px rgba(0,0,0,0.2);
}

Part 8: Create more items

  1. Before duplicating the item, create a items-container div class that contains all the items.

  2. To avoid any hassle, you should fold your code in Sublime Text.

  3. First, locate the container class, it is under banner image.

  4. Move your cursor to the line number, very left side of the editor.

  5. An arrow will appear, click the one next to container class and it will collapse everything inside.

  6. Now, you can add the items-container class without scrolling all the way to the bottom.

    <div class="items-container">
	<!-- container class starts here -->
	<div class="container"> 
	...
	<!-- container class ends here -->
	</div>
</div>

  7. You can easily duplicate the items now, just highlight the container class, copy and paste.

  8. After you're done, you will notice that the items sorts in only one column.

  9. To fix that, go to style.css and locate container class, change display value to inline-block.

  10. Also, change the margin from auto to 10px.

    .container {
	margin: 10px;
	display: inline-block; 
	/* allows the element to have height and width but still acts as inline */
	...
}

  11. All the items will move to the left now, to center it, use the items-container class you've created.

    .items-container {
	text-align: center;
}

Part 9: Adding a footer

  1. Go to accessories.html and scroll to the bottom, add a footer tag above the closing body tag.

    	...
	<footer><p> Copyright © Sunway Tech Club 2018 </p></footer>
</body>

  2. Go back to style.css and create a footer selector.

  3. Add background-color, height, color and text-align properties.

  4. Set it as a block display and add some paddings at the top.

    footer {
	background-color: #394258;
	height: 70px;
	color: lightgrey;
	text-align: center;

	display:block;
	padding-top: 90px;
}

  5. Notice the footer did not fill to the edges of the page, to fix this, go to style.css.

  6. Scroll to the top and add a margin property with a value of 0 in the body selector.

    body {
	...
	margin: 0;
}

  7. Now let's add social media icons to the footer. Open accessories.html and add this in the head section.

    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">

  8. The link element above links to an external CSS file from an online source.

  9. Now, scroll down to footer section and add these classes inside.

    <footer>
	<a class="fa fa-facebook"></a>
	<a class="fa fa-instagram"></a>
	<a class="fa fa-twitter"></a>
	<p>Copyright © Sunway Tech Club 2018</p>
</footer>

Part 10: Changing the font

  1. Always leave changing fonts to the last so you can have time to pick the font you prefer.

  2. Go to fonts.google.com to look for fonts.

  3. Some fonts don't look good in paragraph so make sure you select paragraph to check.

  4. I have chosen Alegreya Sans for this demonstration, click the red 'plus' logo at the top right corner.

  5. There will be a bar at the bottom, click to open it and select @import.

  6. Copy the link and paste it at the top-most section of style.css.

  7. Then, add font-family property in body selector to apply the font.

    @import url('https://fonts.googleapis.com/css?family=Alegreya+Sans');
body {
	...
	font-family: 'Alegreya Sans', sans-serif;
}

  8. Congratulations! You have completed all the parts.
