 // 👉 3- Changing an element's text content
 //  A- Change the cat-related content into dog-related content

 //  B- Have the students research online the difference between textContent and innerText

 // 👉 4- Changing any property
 //  A- Using dot notation to change a few attributes
+document.querySelector(`Card-Subtitle`).attributes(`New Title`, `Is this right?`)
 //  B- Using .setAttribute to change a few attributes
-
+document.querySelector(`img.card-img-top`).setAttribute(`alt`, `dogs are people/s best friend`)
 
 // 👉 5- Changing the styling of an element
 //  A- By changing the class names on the element with the classList API
+header.classList.
 //  B- By manipulating inline styles on the element
+const h2 = document.querySelector(`h2.card-title`)

 // 👉 6- Creating new elements from scratch and appending them
 // Create a new link inside the nav for "Blog"
-

 // DOM nodes can only exist in one spot in the DOM
 // We cannot append the same copy multiple times
