Where is the option to underline headlines and subheadlines in posts/pages?

I can only see bold or itallics in the kitchen sink menu above each post/page!! Where is the option to underline headlines or subheadlines in the post and page editor?

Hi Sunil,

Thank you for your question.

The WordPress only provides strikethough line button and not underline button.

To add underline you have to develop custom CSS code using text-decoration property and add it in the Custom CSS option of the latest version of Sparkling theme on the below path.

Admin Area -> Appearance -> Customize -> Sparkling Options -> Other -> Custom CSS

Thanks. What is the custom CSS code to create the underline option?

You can try using below custom CSS code.

h1, h2 {
    text-decoration: underline;
}

It wasn’t the H1 and H2 tags that I want to underline as they already stand out.
Is there a way of underlining key sections of the paragraph text?

Could you please share me the page URL from your site where the key sections are displaying so that i can help you to achieve it?

Or just change the tags h1, h2 in the above code to whatever you want to.
