CSS不显示边框，为什么？

Question

I tried to add a border to the input but the border doesn't display. I don't know what the problem could be. Does anyone see something that I don't?

HTML:

<div class="word">
  <div class="search">
    <span class="text">Search</span>
       <input type="text" placeholder="Enter word to search">
       <button><i class="fas fa-search"></i></button>
    </div>
</div>

And CSS:

.word .search input{
   position: absolute;
   height: 42px;
   width: calc(100% - 50px);
   font-size: 16px;
   padding: 0 13px;
   border: 1px solid #e6e6e6 !important;
   outline: none;
   border-radius: 5px 0 0 5px;
   opacity: 0;
   pointer-events: none;
   transition: all 0.2s ease;
}

Answer 1

just remove the opacity or make it 1

<div class="word">
  <div class="search">
    <span class="text">Search</span>
       <input type="text" placeholder="Enter word to search">
       <button><i class="fas fa-search"></i></button>
    </div>
</div>
<style>
.word .search input{
   position: absolute;
   height: 42px;
   width: calc(100% - 50px);
   font-size: 16px;
   padding: 0 13px;
   border: 1px solid #e6e6e6 !important;
   outline: none;
   border-radius: 5px 0 0 5px;
   /*opacity: 0;*/
   pointer-events: none;
   transition: all 0.2s ease;
}
</style>

Answer 2

I am not sure I understand precisely what you are trying to do but as stated in previous answers if you set the opacity to 0 the entire input including the border will be transparent/not visible. The search bar doesn't seem to do much in the code you provided as the pointer-events: none; results in the search bar being impossible to select.

So if you want a search bar with a border but with a transparent background, and it being clickable I would suggest the following:

 .word{ background: lightgrey; }.search input{ border: 2px solid #000; border-radius: 5px 0 0 5px; background: transparent; }

 <div class="word"> <div class="search"> <span class="text">Search</span> <input type="text" placeholder="Enter word to search"> <button><i class="fas fa-search"></i>button</button> </div> </div>
