Block interface

To reveal the block toolbar, you can click on the block, and the toolbar will display. Each block comes with unique toolbar icons and specific user controls that allow you to manipulate the block right in the editor.

The alert block offers basic formatting options in its toolbar such as align text left, center, and right, and to format text as bold, italicize, hyperlinks, or strike through.

Predefined alert types

The predefined alert type provides 5 default alert message box styles: “Default”, “Success”, “Info”, “Warning”, and “Error”. Each of these styles provides a default icon and color.

On this tab, the controls allow you to change the icon and alert message content’s font size, either with relative percentages or down to the pixel.

Border settings

The border setting tab gives you the ability to add a simple border to the left side of the alert. This can be combined with different text and background colors, and alert type to provide unique accents to the message box.

Border settings in alert block

You need to specify the width of the border size by using one of the three predefined values: “Thin”, “Medium”, or “Thick”.

In addition to that, you can define the radius of the alert message box’s corners with selecting one of the two available predefined values: “Edge”, “Pill”. Unlike the border width setting, the changes applied by selecting any of the radius values will apply to all four sides of the message box.

Color settings

You can choose the text and background colors for your alert message content. Moreover, the icon and border color of the alert box is customizable and can be refined upon your choice.
