This page describes how to style text in the contents of the page which is visually emphasized.

[#bold]
== Bold text (<strong>)

How xref:antora:asciidoc:bold.adoc[text marked as bold] appears on your site depends on the fonts loaded by the UI and the CSS styles the UI applies to the `<strong>` HTML tag.

[source,html]
----
A bold <strong>word</strong>, or a bold <strong>phrase of text</strong>.
----

Since `<strong>` is a semantic HTML element, it automatically inherits default styling (`font-weight: bold`) from the browser.
If you want to override the browser styles, you'll need to define properties on the `strong` selector in the stylesheet for your UI.

In the default UI, the `<strong>` element is styled in the 500 font weight of the current typeface (Roboto).
For example:

[example]
A bold *word*, or a bold *phrase of text*.

[#italic]
== Italic text (<em>)

How xref:antora:asciidoc:italic.adoc[italicized text] appears on your site depends on the fonts loaded by the UI and the CSS styles the UI applies to the `<em>` HTML tag.

[source,html]
----
An italic <em>word</em>, or an italic <em>phrase of text</em>.
----

Since `<em>` is a semantic HTML element, it automatically inherits default styling (`font-style: italic`) from the browser.
If you want to override the browser styles, you'll need to define properties on the `em` selector in the stylesheet for your UI.

In the default UI, the `em` element is styled in the italic font variant of the current typeface (Roboto).
For example:

[example]
An italic _word_, or an italic _phrase of text_.
