## Import Packages
20+
To start using Aspose.HTML for Java, you'll need to import the necessary packages into your Java class. Here's how to set up your imports:
1221
```java
13-
package com.aspose.html.documentation.examples;
14-
15-
public class WorkingWithHTMLDocuments_EditDocuments_InlineCSS {
16-
public static void main(String [] args) throws java.io.IOException {
17-
// START_SNIPPET WorkingWithHTMLDocuments_EditDocuments_InlineCSS
18-
// Create an instance of an HTML document with specified content
19-
String content = "<p> Inline CSS </p>";
20-
com.aspose.html.HTMLDocument document = new com.aspose.html.HTMLDocument(content, ".");
21-
22-
// Find the paragraph element to set a style attribute
23-
com.aspose.html.HTMLElement paragraph = (com.aspose.html.HTMLElement) document.getElementsByTagName("p").get_Item(0);
24-
25-
// Set the style attribute
26-
paragraph.setAttribute("style", "font-size: 250%; font-family: verdana; color: #cd66aa");
27-
28-
// Save the HTML document to a file
29-
document.save("edit-inline-css.html");
30-
31-
// Create the instance of the PDF output device and render the document into this device
32-
com.aspose.html.rendering.pdf.PdfDevice device = new com.aspose.html.rendering.pdf.PdfDevice("edit-inline-css.pdf");
33-
document.renderTo(device);
34-
// END_SNIPPET
35-
}
36-
}
37-
22+
import com.aspose.html.HTMLDocument;
23+
import com.aspose.html.HTMLElement;
24+
```
25+
These imports bring in the classes required to create an HTML document, manipulate elements, and render the output as a PDF.
26+
## Step 1: Create an HTML Document
27+
The first step in adding inline CSS to an HTML document is to create the document itself. This document will be your canvas, and it can be as simple or as complex as you like. For this tutorial, we'll start with a basic paragraph element.
28+
```java
29+
String content = "<p>Inline CSS Example</p>";
30+
com.aspose.html.HTMLDocument document = new com.aspose.html.HTMLDocument(content, ".");
3831
```
32+
In this step, you're creating an `HTMLDocument` object from a string containing your HTML content. The second argument `"."` indicates the base URL, which in this case, is the current directory.
33+
## Step 2: Locate the Paragraph Element
34+
Now that your document is set up, the next step is to find the HTML element you want to style. In this case, we're focusing on the `<p>` element.
35+
```java
36+
com.aspose.html.HTMLElement paragraph = (com.aspose.html.HTMLElement) document.getElementsByTagName("p").get_Item(0);
37+
```
38+
Here, you're accessing the first `<p>` element in the document using `getElementsByTagName`. The method returns a list of elements, and `get_Item(0)` grabs the first one in the list.
39+
## Step 3: Apply Inline CSS
40+
With the paragraph element in hand, it's time to add some style. Inline CSS is perfect for small, specific tweaks directly within the HTML element.
41+
```java
42+
paragraph.setAttribute("style", "font-size: 250%; font-family: verdana; color: #cd66aa");
43+
```
44+
In this step, the `setAttribute` method is used to add a `style` attribute to the paragraph element. The CSS styles are written as a string, setting the font size, font family, and text color.
45+
## Step 4: Save the HTML Document
46+
After applying your styles, you'll likely want to save the modified HTML document. This can be done easily with the `save` method provided by Aspose.HTML for Java.
47+
```java
48+
document.save("edit-inline-css.html");
49+
```
50+
Here, you're saving the HTML document with the inline CSS to a file named `edit-inline-css.html` in the current directory. This allows you to view the styled HTML content in a browser.
51+
## Step 5: Render the HTML Document as PDF
52+
Finally, if you want to convert your styled HTML document into a PDF, Aspose.HTML for Java has got you covered. This is particularly useful if you need a print-ready version of your document.
53+
```java
54+
com.aspose.html.rendering.pdf.PdfDevice device = new com.aspose.html.rendering.pdf.PdfDevice("edit-inline-css.pdf");
55+
document.renderTo(device);
56+
```
57+
In this final step, you create a `PdfDevice` instance, specifying the output file name as `edit-inline-css.pdf`. Then, you render the HTML document to this PDF device, effectively converting your HTML to a PDF file.
58+
59+

60+
And that's it! You've just learned how to add inline CSS to an HTML document using Aspose.HTML for Java. This powerful library makes it easy to manipulate HTML content and export it to various formats, including PDF. Whether you're automating document generation or working on a web-based project, this tool offers the flexibility and power you need.
61+
## FAQ's
62+
### Can I apply multiple styles using inline CSS?
63+
Yes, you can apply multiple styles by separating each CSS property with a semicolon within the `setAttribute` method.

24+

25+
import java.nio.file.Paths;
26+
import java.io.IOException;
27+
```
28+
These lines import the core classes you’ll be using to work with HTML documents and files in Java.
29+
## Step 1: Prepare Your External CSS Content
30+
The first step in our journey is to prepare the CSS content that will be used to style your HTML document. This involves defining the styles for various HTML elements.
31+
```java
32+
String styleContent = ".flower1 { width:120px; height:40px; border-radius:20px; background:#4387be; margin-top:50px; } \r\n" +
33+
".flower2 { margin-left:0px; margin-top:-40px; background:#4387be; border-radius:20px; width:120px; height:40px; transform:rotate(60deg); } \r\n" +
34+
".flower3 { transform:rotate(-60deg); margin-left:0px; margin-top:-40px; width:120px; height:40px; border-radius:20px; background:#4387be; }\r\n" +
35+
".frame { margin-top:-50px; margin-left:310px; width:160px; height:50px; font-size:2em; font-family:Verdana; color:grey; }\r\n";
36+
```
37+
Here, we define CSS classes (`flower1`, `flower2`, `flower3`, and `frame`) with specific properties such as width, height, background color, and transformations.
38+
## Step 2: Write CSS to an External File
39+
After defining your CSS content, the next step is to write this content to an external CSS file. This file will be linked to your HTML document.
40+
```java
41+
Files.write(Paths.get("flower.css"), styleContent.getBytes());
42+
```
43+
This line of code writes the `styleContent` string to a file named `flower.css`. The `Files.write` method is a convenient way to create a new file and fill it with content in one go.
44+
## Step 3: Create an HTML Document and Link the CSS File
45+
With your external CSS file ready, it's time to create an HTML document that will utilize these styles. Here’s how you can do it:
46+
```java
47+
String htmlContent = "<link rel=\"stylesheet\" href=\"flower.css\" type=\"text/css\" /> \r\n" +
48+
"<div style=\"margin-top: 80px; margin-left:250px; transform: scale(1.3);\" >\r\n" +
49+
"<div class=\"flower1\" ></div>\r\n" +
50+
"<div class=\"flower2\" ></div>\r\n" +
51+
"<div class=\"flower3\" ></div></div>\r\n" +
52+
"<div style = \"margin-top: -90px; margin-left:120px; transform:scale(1);\" >\r\n" +
53+
"<div class=\"flower1\" style=\"background: #93cdea;\"></div>\r\n" +
54+
"<div class=\"flower2\" style=\"background: #93cdea;\"></div>\r\n" +
55+
"<div class=\"flower3\" style=\"background: #93cdea;\"></div></div>\r\n" +
56+
"<div style =\"margin-top: -90px; margin-left:-80px; transform: scale(0.7);\" >\r\n" +
57+
"<div class=\"flower1\" style=\"background: #d5effc;\"></div>\r\n" +
58+
"<div class=\"flower2\" style=\"background: #d5effc;\"></div>\r\n" +
59+
"<div class=\"flower3\" style=\"background: #d5effc;\"></div></div>\r\n" +
60+
"<p class=\"frame\">External</p>\r\n" +
61+
"<p class=\"frame\" style=\"letter-spacing:10px; font-size:2.5em \"> CSS </p>\r\n";
62+
com.aspose.html.HTMLDocument document = new com.aspose.html.HTMLDocument(htmlContent, ".");
63+
```
64+
This snippet creates an HTML document with content that includes a reference to the external CSS file (`flower.css`). The HTML structure consists of several `div` elements styled by the CSS classes defined earlier.
65+
## Step 4: Save the HTML Document to a File
66+
Finally, once your HTML document is ready, you’ll need to save it to a file. This step will allow you to view the HTML content in a web browser or use it in your web applications.
67+
```java
68+
document.save("edit-external-css.html");
5269
```
70+
The `document.save` method saves the HTML document to a file named `edit-external-css.html`. This file will display your styled HTML content when opened in any browser.
71+
## Conclusion
72+
