To hide the scroll bar if not needed with CSS, we set the overflow-y property.

For instance, we write

div {
  overflow-y: auto;
}

to only show the vertical scrollbar only when needed with overflow-y: auto;.

To turn off word wrapping in CSS, we set thr white-space property.

For instance, we write

div {
  white-space: pre-wrap;
}

to add the white-space: pre-wrap; style to turn off word wrapping in the div.

To vertically align text inside a flexbox with CSS, we set the align-items property.

For instance, we write

ul {
  height: 100%;
}

li {
  display: flex;
  justify-content: center;
  align-items: center;
  background: silver;
  width: 100%;
  height: 20%;
}

to add align-items: center; to vertically center align the content in the li element.

We make li elements flex containers with display: flex;.

To select elements with two classes with CSS, we add both class selectors.

For instance, we werite

.foo.bar {
  color: red;
}

to add select elements with both the foo and bar class applied and set their content color to red.

To fix CSS text-overflow: ellipsis; not working, we should apply the text-overflow style to an inline-block element.

For instance, we write

.app a {
  height: 18px;
  width: 140px;
  padding: 0;
  overflow: hidden;
  position: relative;
  display: inline-block;
  margin: 0 5px 0 5px;
  text-align: center;
  text-decoration: none;
  text-overflow: ellipsis;
  white-space: nowrap;
  color: #000;
}

to make the a elements inline block with display: inline-block;.

Then we can apply the text-overflow: ellipsis; style.
