Otf шрифты для css

CSS Web Fonts

Web fonts allow Web designers to use fonts that are not installed on the user’s computer.

When you have found/bought the font you wish to use, just include the font file on your web server, and it will be automatically downloaded to the user when needed.

Your «own» fonts are defined within the CSS @font-face rule.

Different Font Formats

TrueType Fonts (TTF)

TrueType is a font standard developed in the late 1980s, by Apple and Microsoft. TrueType is the most common font format for both the Mac OS and Microsoft Windows operating systems.

OpenType Fonts (OTF)

OpenType is a format for scalable computer fonts. It was built on TrueType, and is a registered trademark of Microsoft. OpenType fonts are used commonly today on the major computer platforms.

The Web Open Font Format (WOFF)

WOFF is a font format for use in web pages. It was developed in 2009, and is now a W3C Recommendation. WOFF is essentially OpenType or TrueType with compression and additional metadata. The goal is to support font distribution from a server to a client over a network with bandwidth constraints.

The Web Open Font Format (WOFF 2.0)

TrueType/OpenType font that provides better compression than WOFF 1.0.

SVG Fonts/Shapes

SVG fonts allow SVG to be used as glyphs when displaying text. The SVG 1.1 specification define a font module that allows the creation of fonts within an SVG document. You can also apply CSS to SVG documents, and the @font-face rule can be applied to text in SVG documents.

Embedded OpenType Fonts (EOT)

EOT fonts are a compact form of OpenType fonts designed by Microsoft for use as embedded fonts on web pages.

Browser Support for Font Formats

The numbers in the table specifies the first browser version that fully supports the font format.

Font format
TTF/OTF	9.0*	4.0	3.5	3.1	10.0
WOFF	9.0	5.0	3.6	5.1	11.1
WOFF2	14.0	36.0	39.0	10.0	26.0
SVG	Not supported	Not supported	Not supported	3.2	Not supported
EOT	6.0	Not supported	Not supported	Not supported	Not supported

*IE: The font format only works when set to be «installable».

Using The Font You Want

In the @font-face rule; first define a name for the font (e.g. myFirstFont) and then point to the font file.

Tip: Always use lowercase letters for the font URL. Uppercase letters can give unexpected results in IE.

To use the font for an HTML element, refer to the name of the font (myFirstFont) through the font-family property:

Example

@font-face <
font-family: myFirstFont;
src: url(sansation_light.woff);
>

div font-family: myFirstFont;
>

Using Bold Text

You must add another @font-face rule containing descriptors for bold text:

Example

The file «sansation_bold.woff» is another font file, that contains the bold characters for the Sansation font.

Browsers will use this whenever a piece of text with the font-family «myFirstFont» should render as bold.

This way you can have many @font-face rules for the same font.

CSS Font Descriptors

The following table lists all the font descriptors that can be defined inside the @font-face rule:

Descriptor	Values	Description
font-family	name	Required. Defines a name for the font
src	URL	Required. Defines the URL of the font file
font-stretch	normal condensed ultra-condensed extra-condensed semi-condensed expanded semi-expanded extra-expanded ultra-expanded	Optional. Defines how the font should be stretched. Default is «normal»
font-style	normal italic oblique	Optional. Defines how the font should be styled. Default is «normal»
font-weight	normal bold 100 200 300 400 500 600 700 800 900	Optional. Defines the boldness of the font. Default is «normal»
unicode-range	unicode-range	Optional. Defines the range of UNICODE characters the font supports. Default is «U+0-10FFFF»

Подключение шрифтов в CSS

Если не вникать в подробности, по быстрому подключить шрифт можно так:

/* Обычный */ @font-face < font-family: 'FontName'; src: url(/fonts/font.ttf); >/* Жирный */ @font-face < font-family: 'FontName bold'; src: url(/fonts/font-bold.ttf); >.text-1 < font-family: 'FontName'; font-size: 20px; >.text-2

Такой метод вполне работает в большинстве браузеров, но неверен. В данном примере упущено:

• Нет названия шрифта в свойстве local .
• Подключен только один формат шрифта.
• Неправильно настроены начертания.

Локальные шрифты

Правило @font-face src позволяет задать название локального шрифта, т.е. если у пользователя на компьютере уже установлен нужный шрифт, то будет использоваться именно он, при этом существенно увеличится скорость загрузки и отрисовки страницы.

Можно указать несколько названий:

Форматы шрифтов

Сегодня используются четыре формата, рассмотрим их подробнее:

TTF/OTF – работают в большинстве браузеров, кроме IE.

EOT – создан Microsoft, представляет сжатую копию шрифта TTF, поддерживается только в IE.

WOFF – формат представляет собой сжатый шрифт в формате TTF/OTF.

WOFF2 – имеет улучшенное сжатие, по сравнению с первой версией.

Как видно нет единого формата, который поддерживается всеми браузерами, поэтому нужно делать подключение нескольких файлов, браузер сам выберет подходящий формат. Рекомендуется подключать файлы шрифтов по приоритету:

• WOFF2 для современных браузеров.
• WOFF для браузеров, которые не поддерживают WOFF2.
• TTF для устаревших браузерах
• EOT для поддержки IE.

Если в наборе есть не все форматы, их можно получить перекодировкой с помощью сервисов onlinefontconverter.com или convertio.co.

@font-face

The @font-face CSS at-rule specifies a custom font with which to display text; the font can be loaded from either a remote server or a locally-installed font on the user’s own computer.

Syntax

@font-face  font-family: "Trickster"; src: local("Trickster"), url("trickster-COLRv1.otf") format("opentype") tech(color-COLRv1), url("trickster-outline.otf") format("opentype"), url("trickster-outline.woff") format("woff"); > 

Descriptors

Defines the ascent metric for the font.

Defines the descent metric for the font.

Determines how a font face is displayed based on whether and when it is downloaded and ready to use.

Specifies a name that will be used as the font face value for font properties.

A font-stretch value. Accepts two values to specify a range that is supported by a font-face, for example font-stretch: 50% 200%;

A font-style value. Accepts two values to specify a range that is supported by a font-face, for example font-style: oblique 20deg 50deg;

A font-weight value. Accepts two values to specify a range that is supported by a font-face, for example font-weight: 100 400;

Note: The font-variant descriptor was removed from the specification in 2018. The font-variant value property is supported, but there is no descriptor equivalent.

Allows control over advanced typographic features in OpenType fonts.

Allows low-level control over OpenType or TrueType font variations, by specifying the four letter axis names of the features to vary, along with their variation values.

Defines the line gap metric for the font.

Defines a multiplier for glyph outlines and metrics associated with this font. This makes it easier to harmonize the designs of various fonts when rendered at the same font size.

Specifies references to font resources including hints about the font format and technology. It is required for the @font-face rule to be valid.

The range of Unicode code points to be used from the font.

Description

It’s common to use both url() and local() together, so that the user’s installed copy of the font is used if available, falling back to downloading a copy of the font if it’s not found on the user’s device.

If the local() function is provided, specifying a font name to look for on the user’s device, and if the user agent finds a match, that local font is used. Otherwise, the font resource specified using the url() function is downloaded and used.

Browsers attempt to load resources in their list declaration order, so usually local() should be written before url() . Both functions are optional, so a rule block containing only one or more local() without url() is possible. If a more specific fonts with format() or tech() values are desired, these should be listed before versions that don’t have these values, as the less-specific variant would otherwise be tried and used first.

By allowing authors to provide their own fonts, @font-face makes it possible to design content without being limited to the so-called «web-safe» fonts (that is, the fonts which are so common that they’re considered to be universally available). The ability to specify the name of a locally-installed font to look for and use makes it possible to customize the font beyond the basics while making it possible to do so without relying on an internet connection.

Note: Fallback strategies for loading fonts on older browsers are described in the src descriptor page.

The @font-face at-rule may be used not only at the top level of a CSS, but also inside any CSS conditional-group at-rule.

Font MIME Types

Format	MIME type
TrueType	font/ttf
OpenType	font/otf
Web Open Font Format	font/woff
Web Open Font Format 2	font/woff2

Notes

• Web fonts are subject to the same domain restriction (font files must be on the same domain as the page using them), unless HTTP access controls are used to relax this restriction.
• @font-face cannot be declared within a CSS selector. For example, the following will not work:

.className  @font-face  font-family: "MyHelvetica"; src: local("Helvetica Neue Bold"), local("HelveticaNeue-Bold"), url("MgOpenModernaBold.ttf"); font-weight: bold; > > 

Formal syntax

Examples

Specifying a downloadable font

This example specifies a downloadable font to use, applying it to the entire body of the document:

doctype html> html lang="en-US"> head> meta charset="utf-8" /> meta name="viewport" content="width=device-width" /> title>Web Font Sampletitle> style media="screen, print"> @font-face  font-family: "Bitstream Vera Serif Bold"; src: url("https://mdn.github.io/css-examples/web-fonts/VeraSeBd.ttf"); > body  font-family: "Bitstream Vera Serif Bold", serif; > style> head> body> This is Bitstream Vera Serif Bold. body> html> 

The output of this example code looks like so:

Specifying local font alternatives

In this example, the user’s local copy of «Helvetica Neue Bold» is used; if the user does not have that font installed (both the full font name and the Postscript name are tried), then the downloadable font named «MgOpenModernaBold.ttf» is used instead:

@font-face  font-family: "MyHelvetica"; src: local("Helvetica Neue Bold"), local("HelveticaNeue-Bold"), url("MgOpenModernaBold.ttf"); font-weight: bold; >
