Alignment at both ends is very commonly used in the production of navigation Nav. This article will introduce in detail the 3 implementation methods of CSS alignment at both ends
PHONEFlexible box model As a powerful elastic layout method, flex can hold most layouts Effects, of course, include alignment. If you want Considering the compatibility of the three versions of flex, use the following code <a href="http://www.php.cn/wiki/109.html" target="_blank"> [Note] IE9-browser does not support </a><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:css;toolbar:false;">justify-content: space-between;</pre><div class="contentsignin">Copy after login</div></div>text-align Horizontal Alignment
itself has an attribute value of aligning both ends
justify. However, it should be noted that when using it to achieve alignment at both ends, you need to pay attention to adding whitespace characters (including spaces, newlines, and tabs) between elements for it to work. Since there are line breaks between
Elements must occupy a full line, as shown below. Elements that fill up a row can be aligned at both ends, but elements that do not fill up cannot be aligned 【text-align-last】 Obviously, none of the above situations meet the requirements. At this time, You need to use the attribute text-align-last, which is used to specify how to align the last line of text.
So replace the
text-alignattribute with
text -align-last. However, to be compatible with
IE browser, you need to set text-align:justify
at the same time [Note] Safari browser, IOS, androis4.4-browser does not support <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:css;toolbar:false;">.justify-content_flex-justify{
-webkit-box-pack: justify;

justify-content: space-between;

.in{background-color: lightblue;padding: 0 10px;}
.display_flex{display: -webkit-box;display: -ms-flexbox;display: -webkit-flex;display: flex;}

<li class="in">样式</li>
<li class="in">行为</li>
</ul></pre><div class="contentsignin">Copy after login</div></div>【after pseudo-element】 Using text-align-last can achieve the effect of aligning both ends, but the compatibility is not good. By setting the pseudo element :after
to the parent element, and setting
inline-blockto the pseudo element, and setting the width to 100%, it is equivalent to the pseudo element
:after is squeezed to the second line. As a result, the original element occupies the first line, triggering the effect of aligning both ends It should be noted here that because the blank space will be parsed as a newline, you can set the height of the parent element height<a href="http://www.php.cn/wiki/978.html" target="_blank">, and overflow and hide to solve the problem of redundant line breaks</a><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:css;toolbar:false;"><style>

defines the number of columns of the element. In the example, there are 3 sub-elements, so it is defined as 3 columns. Special attention should be paid to the fact that the child elements need to be set as block elements at this time for it to take effect. [Note] IE9-browser does not support
