amp-fit-text

Introduction

amp-fit-text enables you to manage the size and fit of text within a given area.

Setup

Include the amp-fit-text component.

<script async custom-element="amp-fit-text" src="https://cdn.ampproject.org/v0/amp-fit-text-0.1.js"></script>

Basic usage

In each of these examples, the amp-fit-text element is nested within a container with fixed dimensions to demonstrate the differences in attributes and layout values. When amp-fit-text is used with a given height, width, and layout="responsive" attribute, the text will scale to fit the parent container.

Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
<div class="square-small">
  <amp-fit-text width="1"
    height="1"
    layout="responsive">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-medium">
  <amp-fit-text width="1"
    height="1"
    layout="responsive">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-large">
  <amp-fit-text width="1"
    height="1"
    layout="responsive">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>

Aspect ratio

The text will scale responsively in the ratio defined by the responsive layout, but not exceed the size of its parent. This sample defines an aspect ratio of 1.5:1 (3:2).

Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
<div class="square-small">
  <amp-fit-text width="300"
    height="200"
    layout="responsive">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-medium">
  <amp-fit-text width="300"
    height="200"
    layout="responsive">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-large">
  <amp-fit-text width="300"
    height="200"
    layout="responsive">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>

min-font-size

The min-font-size attribute dictates a minimum size for the text. In this case, we've dictated a minimum of 30, which will cause it to exceed the size of its fixed block parent and be truncated to fit as appropriate.

Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
<div class="square-small">
  <amp-fit-text width="200"
    height="200"
    layout="responsive"
    min-font-size="18">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-medium">
  <amp-fit-text width="200"
    height="200"
    layout="responsive"
    min-font-size="18">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-large">
  <amp-fit-text width="200"
    height="200"
    layout="responsive"
    min-font-size="18">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>

max-font-size

The max-font-size attribute dictates a maximum size for the text. In this case, we've dictated a maximum of 10, ensuring it won't fill the size of its parent element.

Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.
<div class="square-small">
  <amp-fit-text width="200"
    height="200"
    layout="responsive"
    max-font-size="18">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-medium">
  <amp-fit-text width="200"
    height="200"
    layout="responsive"
    max-font-size="18">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
<div class="square-large">
  <amp-fit-text width="200"
    height="200"
    layout="responsive"
    max-font-size="18">Lorem ipsum dolor sit amet, has nisl nihil convenire et, vim at aeque inermis reprehendunt.</amp-fit-text>
</div>
