1//! This module defines the `HtmlBuilder` structure and related functions
2//! for generating HTML components with embedded CSS styles.
3//!
4//! The `HtmlBuilder` allows users to build a webpage by specifying various
5//! components such as containers, text, and icons, and applying custom CSS
6//! styles. It provides methods for importing fonts, disabling default browser
7//! CSS, and rendering the components into HTML strings.
8//!
9//! The components are modular, and the builder pattern is used to allow for
10//! easy chaining of method calls to configure and generate the final output.
