css prevents text from wrapping

In web design and development, we usually need to control the layout and style of page elements. One of the more common problems with text layout is how to prevent text from wrapping. This article will introduce some common methods in CSS to help you solve this problem.

1. white-space attribute

white-spaceThe attribute determines how to handle the white space in the element box. It has 5 optional values: normal , nowrap, pre, pre-wrap, pre-line. Their effects are:

• normal: Default value, merge excess blanks, text will not wrap, text will automatically wrap if it cannot fit on one line;
• nowrap: No line breaks, which is equivalent to combining the features of normal and pre;
• pre: Reserved Excess white space, no merging, no line wrapping. If you need to wrap a line, you need to add `
  ` manually;
• pre-wrap: Keep excess white space, no merging, and automatic line wrapping, if necessary. In the case of line wrapping, it will be automatically wrapped;
• pre-line: Merge excess blanks, and the text will be automatically wrapped if it cannot fit on one line.

Therefore, when we need to prevent text from wrapping automatically, we can use white-space: nowrap.

div {
  white-space: nowrap;
}

Of course, if you want to retain excess blanks, you can also use other values. For example, if you want the text to appear completely on one line, you can use white-space: pre.

div {
  white-space: pre;
}

2. word-break attribute

After setting the white-space attribute, if the text length exceeds the width of the box, it will automatically wrap. At this time, you need to use the word-break attribute to control the line breaking of text. It has three optional values: normal, break-all, keep-all. Their effects are:

• normal: Default value, line breaks between words according to standard word breaking rules;
• break -all: Break lines between words, and do not consider any rules for line breaking within English words;
• keep-all: Break lines between words, but within English words Keep doing it.

Therefore, you can prevent text from automatically wrapping by setting the value of the word-break attribute to keep-all.

div {
  white-space: nowrap;
  word-break: keep-all;
}

3. overflow attribute

In some cases, even if the correct text layout is set through the white-space and word-break attributes way, the text length may also exceed the width of the box. At this time, you need to use the overflow attribute to control the overflow effect of the text. The overflow attribute has 4 optional values: visible, hidden, scroll, auto. Their effects are:

• visible: Default value, no processing is performed, allowing content beyond the box range to be displayed outside the box;
• hidden: The overflow part is hidden and invisible;
• scroll: The scroll bar is displayed, and the user can view the overflow part through the scroll bar;
• auto : Display scroll bars according to actual needs.

If you want the text to be displayed on one line without automatic line wrapping, and the overflow part is hidden, you can use the white-space and overflow properties in combination.

div {
  white-space: nowrap;
  overflow: hidden;
}

4. text-overflow attribute

When using the overflow: hidden attribute to hide the text overflow part, it may cause the user not to see the complete text content. At this time, you can use the text-overflow attribute to control the overflow effect of text. The text-overflow attribute has two optional values: clip, ellipsis. Their effects are:

• clip: truncate the text and hide the excess part without adding ellipsis;
• ellipsis : Truncate the text, hide the excess part, and add ellipsis symbols (...).

Therefore, you can truncate overly long text and add ellipses by setting the value of the text-overflow attribute to ellipsis.

div {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

5. Use pseudo-elements

In addition to the above methods, you can also control text not to wrap automatically by using pseudo-elements in CSS. For example, you can use "
