The website appears to be using Bootstrap version 4.3.1, which is a popular front-end development framework. The copyright notice indicates that the Bootstrap authors hold the copyright for the framework, with Twitter also having some licensing rights. The site utilizes various fonts including Roboto, Helvetica Neue, Arial, Noto Sans, Serif Apple Color Emoji, Segoe Emoji, Segoe Symbol and Noto Color Mono Courier. It then goes on to define different styles for tables such as solid colored borders and table headers with specific colors like primary, secondary, success, info, warning, danger and light. Additionally, it sets box-shadow properties for an element with padding and border radius values. Based on this information alone, it is difficult to determine the exact nature or purpose of the website as it only provides HTML code snippets related to styling elements like fonts and tables.
