CSS Page: A Proposal for Clarifying the 'size' Property

The CSS page specification has been a topic of discussion among web developers and browser vendors for quite some time. One of the key aspects of this specification is the 'size' property, which determines the size of the page. However, there has been a long-standing issue with the 'size' property, which has led to confusion among developers. In this article, we will explore the proposal to make 'size' a legacy alias of a new descriptor, 'page-size', and discuss its potential benefits and implications.

The Current State of the 'size' Property

The 'size' property is used to specify the size of the page, which can be either 'auto' or a specific value. However, the 'size' property has been the subject of controversy due to its ambiguous behavior. The issue at hand is that the 'size' property can be used in different contexts, such as in the <meta> tag or in the CSS @page rule, which can lead to confusion and inconsistent behavior.

The Proposal: Making 'size' a Legacy Alias of 'page-size'

To address the confusion surrounding the 'size' property, a proposal has been put forth to make 'size' a legacy alias of a new descriptor, 'page-size'. This would involve introducing a new property, 'page-size', which would be used to specify the size of the page, and making 'size' a legacy alias of this new property. This would provide a clear and consistent way of specifying the size of the page, and would help to resolve the long-standing issue with the 'size' property.

Benefits of the Proposal

The proposal to make 'size' a legacy alias of 'page-size' has several benefits. Firstly, it would provide a clear and consistent way of specifying the size of the page, which would help to resolve the confusion surrounding the 'size' property. Secondly, it would provide a clear migration path for developers who are currently using the 'size' property, as they would be able to continue using the 'size' property as a legacy alias of the new 'page-size' property. Finally, it would provide a clear and consistent way of specifying the size of the page, which would help to improve the overall user experience.

Implications of the Proposal

The proposal to make 'size' a legacy alias of 'page-size' has several implications. Firstly, it would require changes to the CSS page specification, which would involve introducing a new property, 'page-size', and making 'size' a legacy alias of this new property. Secondly, it would require changes to browser vendors, which would involve updating their browsers to support the new 'page-size' property and the legacy 'size' property. Finally, it would require changes to developers, which would involve updating their code to use the new 'page-size' property and the legacy 'size' property.

In conclusion, the proposal to make 'size' a legacy alias of 'page-size' has several benefits, including providing a clear and consistent way of specifying the size of the page, providing a clear migration path for developers, and improving the overall user experience. However, it also has several implications, including requiring changes to the CSS page specification, browser vendors, and developers. Ultimately, the decision to implement this proposal would depend on the feedback and input from the web development community.

The proposal to make 'size' a legacy alias of 'page-size' is just one of several proposals that have been put forth to address the issues with the CSS page specification. Other proposals include introducing new properties, such as 'page-break' and 'page-margin', and improving the overall user experience. As the web development community continues to evolve and improve, it is likely that new proposals will be put forth to address the issues with the CSS page specification.

Based on the proposal to make 'size' a legacy alias of 'page-size', we recommend the following:

Introduce a new property, 'page-size', which would be used to specify the size of the page.
