text-align-last property defines how the last line of justified text is aligned before a forced line break.
A line break is where inline-level content breaks over into a new line. It can be either a soft wrap break, where it occurs due to wrapping, or a forced line break where it occurs due to explicit line-breaking controls, or due to the start or end of a block.
text-align-last property only affects inline-level content before a forced line break, as it is only concerned with the last line of text.
text-align-last property is designed to work only on text that has a
text-align value of
- Specifies that the text is aligned as per
text-alignis set to
justify. In this case, content is justified if
distributeand start-aligned otherwise.
- The last line is aligned to the start edge of the line box. This is the left side for left-to-right content, and the right side on right-to-left content.
- The last line is aligned to the end edge of the line box. This is the right side for left-to-right content, and the left side on right-to-left content.
- The last line is aligned to the left of the box.
- The last line is aligned to the right of the box.
- The last line is aligned to the center of the box.
- The last line is justified across the box — the text is aligned to both edges of the box.
In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:
- Represents the value specified as the property's initial value.
- Represents the computed value of the property on the element's parent.
- This value acts as either
initial, depending on whether the property is inherited or not. In other words, it sets all properties to their parent value if they are inheritable or to their initial value if not inheritable.

Working Example within an HTML Document
text-align-lastproperty is defined in CSS Text Module Level 3 (W3C Last Call Working Draft 10 October 2013).
The following table provided by Caniuse.com shows the level of browser support for this feature.
For maximum browser compatibility many web developers add browser-specific properties by using extensions such as
-webkit- for Safari, Google Chrome, and Opera (newer versions),
-ms- for Internet Explorer,
-moz- for Firefox,
-o- for older versions of Opera etc. As with any CSS property, if a browser doesn't support a proprietary extension, it will simply ignore it.
This practice is not recommended by the W3C, however in many cases, the only way you can test a property is to include the CSS extension that is compatible with your browser.
The major browser manufacturers generally strive to adhere to the W3C specifications, and when they support a non-prefixed property, they typically remove the prefixed version. Also, W3C advises vendors to remove their prefixes for properties that reach Candidate Recommendation status.
Many developers use Autoprefixer, which is a postprocessor for CSS. Autoprefixer automatically adds vendor prefixes to your CSS so that you don't need to. It also removes old, unnecessary prefixes from your CSS.
You can also use Autoprefixer with preprocessors such as Less and Sass.
