Add svg icon into button with css/html?

问题

I want to have the icon displayed inside the button tag, see code below:

#header-search {
  width: 200px;
  background: @header-color;
  color: white;
  font-size: 12pt;
  border: 0px solid;
  outline: 0;
  vertical-align: -50%;
}

#header-search::-webkit-input-placeholder {
  color: white;
}

#search-button {
  background: #FFFFFF;
  vertical-align: -50%;
}

.header-view-logo {
  vertical-align: middle;
}

#search-icon {
  fill: white;
}

<button id="search-button" />
<svg id="search-icon" class="search-icon" viewBox="0 0 24 24">
    <path d="M15.5 14h-.79l-.28-.27C15.41 12.59 16 11.11 16 9.5 16 5.91 13.09 3 9.5 3S3 5.91 3 9.5 5.91 16 9.5 16c1.61 0 3.09-.59 4.23-1.57l.27.28v.79l5 4.99L20.49 19l-4.99-5zm-6 0C7.01 14 5 11.99 5 9.5S7.01 5 9.5 5 14 7.01 14 9.5 11.99 14 9.5 14z"/>
    <path d="M0 0h24v24H0z" fill="none"/>
</svg>

But the icon is just displayed all over the place really big one, how can i get it to fit inside the button ?

回答1:

Not sure if the button is not closed or just you copied it here and forgot to close it.

#search-button {
  width: 100px;
  height: 50px;
}
    
#search-button svg {
  width: 25px;
  height: 25px;
}

<button id="search-button">
    <svg id="search-icon" class="search-icon" viewBox="0 0 24 24">
        <path d="M15.5 14h-.79l-.28-.27C15.41 12.59 16 11.11 16 9.5 16 5.91 13.09 3 9.5 3S3 5.91 3 9.5 5.91 16 9.5 16c1.61 0 3.09-.59 4.23-1.57l.27.28v.79l5 4.99L20.49 19l-4.99-5zm-6 0C7.01 14 5 11.99 5 9.5S7.01 5 9.5 5 14 7.01 14 9.5 11.99 14 9.5 14z"/>
        <path d="M0 0h24v24H0z" fill="none"/>
    </svg>
 </button>

I've modified your code a bit an put it up at this fiddle.

The two problems were:

You didn't close your button properly, it needs to end after the SVG
You needed to specify a width for the button (As you can see I left off some of your other CSS)

I suggest you, doing it this way:

.search > div, .search > button {
    display: inline-block;
    vertical-align: middle;
}
#header-search{
    margin: 0;
    line-height: 0;
}
#search-button svg {
  width: 12px;
  height: 12px;
}

<div class="search">
    <input id="header-search" type="search" placeholder="Search..." />
    <button id="search-button">
        <svg id="search-icon" class="search-icon" viewBox="0 0 24 24">
            <path d="M15.5 14h-.79l-.28-.27C15.41 12.59 16 11.11 16 9.5 16 5.91 13.09 3 9.5 3S3 5.91 3 9.5 5.91 16 9.5 16c1.61 0 3.09-.59 4.23-1.57l.27.28v.79l5 4.99L20.49 19l-4.99-5zm-6 0C7.01 14 5 11.99 5 9.5S7.01 5 9.5 5 14 7.01 14 9.5 11.99 14 9.5 14z"/>
            <path d="M0 0h24v24H0z" fill="none"/>
        </svg>
    </button>
</div>
