## HtmlSaveOptions::get_CssClassNamePrefix method


Specifies a prefix which is added to all CSS class names. Default value is an empty string and generated CSS class names have no common prefix.

```cpp
System::String Aspose::Words::Saving::HtmlSaveOptions::get_CssClassNamePrefix() const
```

## Remarks


If this value is not empty, all CSS classes generated by Aspose.Words will start with the specified prefix. This might be useful, for example, if you add custom CSS to generated documents and want to prevent class name conflicts.

If the value is not **null** or empty, it must be a valid CSS identifier.

## Examples



Shows how to save a document to HTML, and add a prefix to all of its CSS class names. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>(System::String(get_MyDir() + u"Paragraphs.docx"));

auto saveOptions = System::MakeObject<Aspose::Words::Saving::HtmlSaveOptions>();
saveOptions->set_CssStyleSheetType(CssStyleSheetType::External);
saveOptions->set_CssClassNamePrefix(u"myprefix-");

doc->Save(get_ArtifactsDir() + u"HtmlSaveOptions.CssClassNamePrefix.html", saveOptions);

System::String outDocContents = System::IO::File::ReadAllText(get_ArtifactsDir() + u"HtmlSaveOptions.CssClassNamePrefix.html");

ASSERT_TRUE(outDocContents.Contains(u"<p class=\"myprefix-Header\">"));
ASSERT_TRUE(outDocContents.Contains(u"<p class=\"myprefix-Footer\">"));

outDocContents = System::IO::File::ReadAllText(get_ArtifactsDir() + u"HtmlSaveOptions.CssClassNamePrefix.css");

ASSERT_TRUE(outDocContents.Contains(u".myprefix-Footer { margin-bottom:0pt; line-height:normal; font-family:Arial; font-size:11pt; -aw-style-name:footer }"));
ASSERT_TRUE(outDocContents.Contains(u".myprefix-Header { margin-bottom:0pt; line-height:normal; font-family:Arial; font-size:11pt; -aw-style-name:header }"));
```
