Using HTML5 Semantic Elements

• The article element, as described by the W3C, is
– a complete, self-contained composition in a
document, page, application, or site
– independently distributable or reusable, e.g. in
syndication
• The start and end tags of article elements are
<article> and </article>
• Content placed between these tags will appear on
a webpage as part of the article element
Article Element

• Articles may be nested within other HTML
elements, such as the main element, the section
element, or other article elements
• Articles are commonly used to contain news
articles, blog and forum posts, or comments
Article Element (continued 1)

Article Element (continued 2)

• The aside element is used as a sidebar that
contains additional information about a particular
item mentioned within another element
• For example, if an article on a webpage contains a
recipe and a list of ingredients, one could include
an aside element with more information about
one of the key ingredients, such as its origin or
where to purchase it
• It can be nested within article elements or
within main or section elements
Aside Element

Aside Element (continued)

• The section element, as described by the W3C, is
an element that
– represents a generic section of a document or
application. Here, a section is a thematic grouping of
content. The theme of each section should be
identified as a child of the section element
– is not a generic container element. A general rule is
that the section element is appropriate only if the
element’s contents would be listed explicitly in the
document’s outline
Section Element

• The following is an example of a several section
elements nested within an article element
<article>
<h1>Tutorials: Cooking Basics</h1>
<p>Watch our tutorials to learn
the basics of good cooking.</p>
<section>
<h1>Tutorial 1</h1>
<p>Assembling basic kitchen tools.</p>
</section>
…
</article>
Section Element (continued 1)

Section Element (continued 2)

• The figure element is used to group content, such
as illustrations, diagrams, and photos
• According to the W3C, the figure element
represents some flow content that is self-
contained and is typically referenced as a single
unit from the main flow of the document
• A figure element can contain one or more img
elements
Figure and Figure Caption
Elements

• The figure element may contain an optional
figure caption element, which is used to provide a
caption for the figure element
• The start and end tags of the figure caption
element are <figcaption> and </figcaption>
Elements (continued 1)

• The following is an example of the figure
element and the figure caption element
<figure>
<figcaption>New York City
Highlights</figcaption>
<img src="ny1.jpg" alt="Statue of
Liberty">
<img src="ny2.jpg" alt="Central Park">
<img src="ny3.jpg" alt="New York at
Night">
</figure>

• A banner is a graphic that spans the width of a
webpage and usually brands a website, often by
displaying its name or an identifying image
• The CSS3 opacity property specifies the
transparency of an element
• The text-shadow property applies a shadow to
text
– h-shadow value – designates the horizontal position of
the shadow
– v-shadow value – designates the vertical position of
the shadow
Website Layout

• An example of a style rule that applies a text
shadow to an element is shown below
h1 {
text-shadow: 0.2em 0.1em #292933;
}
In this example, a text shadow with a horizontal
position of 0.2em, a vertical position of 0.1em,
and a dark gray color is applied to an h1 element

Figure 7–83
• The float property used within the article style
rule displaces the main element to the banner
image area
• To correct this issue, apply an overflow property
with a value of auto to the main style rule
contained within the tablet media query
– Use overflow: auto; to add a property and value
