How Can I Apply CSS Styles in jsPDF Documents?

jsPDF CSS Styling

While using jsPDF, it may seem difficult to apply CSS styles to the output document. However, there are specific steps you can take to achieve this.

In your provided example, you mentioned using inline, internal, and external CSS without success. Let's delve into why these approaches might not have worked.

Inline and Internal CSS:
Both inline and internal CSS are applied within the HTML document. However, jsPDF does not process HTML or CSS directly. Instead, it reads the HTML content and converts it to a PDF document. Therefore, any inline or internal CSS will not be interpreted by jsPDF.

External CSS:
In your example, you applied an external CSS file with media="print". This approach should work in theory. However, the browser environment in which jsPDF operates may not support this media type.

Alternative Approaches:

Since applying CSS directly through HTML is not supported by jsPDF, you can consider the following alternatives:

• jsPDF API: You can manipulate text attributes such as font size, color, and alignment directly through jsPDF's API. For example:

doc.setFontSize(22);
doc.setTextColor(255, 0, 0);
doc.text(20, 20, 'This is a title');

• HTML Template: You can create an HTML template with the desired styles and pass it to jsPDF using the fromHTML method. However, you need to ensure that jsPDF supports the HTML elements and CSS properties used in the template.

Remember, jsPDF is primarily designed to generate PDF documents from HTML content. It does not fully support CSS styling like a browser would. Nonetheless, by using the aforementioned techniques, you can achieve some level of style control in your jsPDF documents.
