# Fit Value

The Text Fitting system automatically adjusts the font size, weight, and line height of text elements so that they fit
 within their containers. This dynamic resizing is especially useful for responsive layouts where available space
 may vary, ensuring that content is always legible.

### Basic Usage

To enable automatic text resizing, add the `data-value-fit="true"` attribute to your element. For numeric values, this is all you need - the system will automatically adjust the element's
 font size and weight to fit the container width. Text content requires additional configuration (see Text Fitting below).

    <span class="value value--xxxlarge" data-value-fit="true">$1,000,000,000</span>

### Text Fitting

When fitting text content, you must specify a maximum height constraint using the `data-value-fit-max-height` attribute (in pixels).
 This ensures text content stays within both width and height constraints while maintaining readability through
 automatic font size and weight adjustments.

Hello. This is a really long headline that will need to adjust significantly to fit within its container space and look good in a layout. XXXLarge

Hello. This is a medium length headline that fits nicely. XXXLarge
