= Text Styles
:description: The theming language provides keys for aligning, decorating, styling, and transforming text.

[#text-align]
== Text alignment

The `text-align` key is used to align text horizontally within the text box.
It has the same function as the `text-align` property in CSS.
The text can be aligned using the following keywords:

center:: Text is centered within the text box.
justify:: Text is spaced out to align evenly with both sides of the text box.
left:: Text is aligned to the left side of the text box.
right:: Text is aligned to the right side of the text box.
inherit:: *Only applies to the caption text of block images (`image-caption`) and tables (`table-caption`).*
The value `inherit` resolves to the alignment of the block.
Further information about using `inherit` on image caption text and table caption text can be found on xref xref:block-images.adoc#caption-text-align[Block Image Styles] and xref:tables.adoc#caption-text-align[Table Styles], respectively.

The `text-align` key is distinct from the similarly-named `align` key.
The xref:blocks.adoc#align[align key] aligns a block element horizontally within its container.

[#decoration]
== Decoration

The `text-decoration` key specifies the type of decoration, such as an underline, that is applied to the text.
It accepts the following keywords:

line-through:: A line is drawn across the text.
This is commonly referred to as a strikethrough.
none:: Clears an inherited value and no decoration is applied to the text.
underline:: A line is drawn beneath the text.

When a key category allows the `text-decoration` key to be set, you can usually specify a `text-decoration-color` and `text-decoration-width`, too.

[#font-style]
== Font style

The `font-style` key specifies the font variant in a font family that the text should use.
The key accepts the following keywords:

bold:: Text is styled using the bold variant of a font family.
bold_italic:: Text is styled using the bold italic variant of a font family
italic:: Text is styled using the italic variant of a font family.
normal:: Text is styled using the normal font variant in a font family.
normal_italic:: The style of the text is reset to normal, and then the text is styled using the italic variant of a font family.

Usually, you can specify a font style wherever you can set a font family (`font-family`).
The converter uses the values of both keys in combination to locate the correct font within a font stack.

[#transform]
== Transform

The `text-transform` key changes the case of the text.
It accepts the following keywords:

capitalize:: Transforms the first letter of each word to a capital letter.
lowercase:: Transforms all the text to lower case letters.
none:: Clears an inherited value and no case transformation is applied to the text.
smallcaps:: Replaces lowercase Latin letters with their small capital variant.
uppercase:: Transforms all the text to capital letters.

The `text-transform` key can’t be set on the xref:base.adoc[base category].
