CSS clearfix doesn't appear to be functioning properly

I've been experimenting with using clearfix instead of the clear both property, but it's not working as expected. Despite following tutorials, the issue persists.

How can I troubleshoot this and make it function properly?

    * {
        margin: 0;
        padding: 0;
    }
    
  /* .first_div {
       width:50%; 
       height:50%; 
       background-color:red;
       margin: 50px auto;  
       overflow: auto;
     
    }*/
    
    .second_div {
        width:50px; 
        height:50px; 
        background-color:green;
        float: left;
     
     } 
    
    .third_div {
          width:50px; 
        height:50px; 
        background-color:blue;
         
     } 

.clearfix:after { content: "\00A0"; display: block; clear: both; visibility: hidden; line-height: 0; height: 0;}
.clearfix{ display: inline-block;}
html[xmlns] .clearfix { display: block;}
* html .clearfix{ height: 1%;}
.clearfix {display: block}

 
 <body>
  <div class="clearfix"> 
    <div class="second_div">sfddsf</div>
    <div class="third_div">sfdsfds</div>
 </div>

css clearfix

Answer 1

Answer №1

When using the clearfix class on floated elements, it helps clear the floats after the element. It's important to wrap floated elements with it to ensure they remain in the document flow. In the provided example, the third_div is not floated, so there is no need to clear float after it. However, adding the clear: both property on the third_div would clear the float before it, bringing back the second_div into the document flow. Depending on your goal, there are two solutions to consider.

Example 1

If you want elements to display next to each other, you can float them both and wrap them in a clearfix div.

CSS

.second_div {
    width: 50px; 
    height: 50px; 
    background-color: green;
    float: left;
} 
.third_div {
    width: 50px; 
    height: 50px; 
    background-color: blue;
    float: left;
}
.clearfix:after {
    visibility: hidden;
    display: block;
    font-size: 0;
    content: " ";
    clear: both;
    height: 0;
}

HTML

<div class="clearfix"> 
    <div class="second_div">Second div</div>
    <div class="third_div">Third div</div>
</div>

Example 2

If you want to display elements one under the other, you only need to float and wrap one of them, and the other will naturally position itself below in the document flow.

CSS

.second_div {
    width: 50px; 
    height: 50px; 
    background-color: green;
    float: left;
} 
.third_div {
    width: 50px; 
    height: 50px; 
    background-color: blue;
}
.clearfix:after {
    visibility: hidden;
    display: block;
    font-size: 0;
    content: " ";
    clear: both;
    height: 0;
}

HTML

<div class="clearfix"> 
    <div class="second_div">Second div</div>
</div>
<div class="third_div">Third div</div>
