Answer:
<!-- Ashley Jones 5th April, 2020-->
/* Ashley Jones 5th April, 2020 */
Explanation:
Comment tags in HTML and CSS (in programming in general) are used to explain one's codes. They can help to better remember and understand when you want to edit the source code later on.
In HTML, <!-- begin a comment and are ended with --> Whatever comments are made between the tags are usually not displayed in the browser. So to enter name and date in the sp_home_txt.html will be <!-- Ashley Jones 5th April, 2020 -->.
In CSS, /* begin a comment and are ended with */ Everything written within is not interpreted. They also help to explain a code and are usually ignored by a browser. So to enter name and date in the comment section of sp_layout_txt.css when opened in the editor will be /* Ashley Jones 5th April, 2020 */
