How do you add an add image as drop down arrow?
提问by user1324068
I created a application with a drop down arrow, but the size of the arrow is too small.
我创建了一个带有下拉箭头的应用程序，但箭头的大小太小。
So I decided to enlarge the size of the arrow. I need to add an image instead of arrow.
所以我决定放大箭头的大小。我需要添加图像而不是箭头。
Is it possible to add image or resize the arrow?
是否可以添加图像或调整箭头大小？
My current CSS is below.
我当前的 CSS 如下。
.custom-select:after {
content: "a–?";
content-size:20;
position: absolute;
top: -83%;
right: 6%;
bottom: 0;
font-size: 60%;
line-height:30px;
line-width:100px;
padding: 0 10px;
background:#03498A;
color: white;
height:40px;
pointer-events:none;
-webkit-border-radius: 0 6px 6px 0;
-moz-border-radius: 0 6px 6px 0;
border-radius: 0 6px 6px 0;
}
<label class="custom-select" style="width:40%" onClick="birthday()">
<select name="mydropdown" id="gender" placeholder="Gender">
<option value="">Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
</label>

Try this solution, worked for me and looks very nice. It's vital to wrap your element inside the div, and then apply formatting.
试试这个解决方案，对我有用，看起来很不错。将元素包装在 div 中，然后应用格式是至关重要的。
Also, make sure that your arrow picture has a transparent background (or at least the same background color as the dropdown you're using).
此外，请确保您的箭头图片具有透明背景（或至少与您使用的下拉菜单的背景颜色相同）。
The ".drop_list select" CSS may look a bit heavy, but it's all needed (except padding and font-size) to make it look good on all browsers/devices. Tested this on desktop/tablet/mobile phones, and works great. You might need to make a few modifications to the CSS to match your site though.
“.drop_list select” CSS 可能看起来有点重，但它是所有需要的（除了填充和字体大小），以使其在所有浏览器/设备上看起来都很好。在台式机/平板电脑/手机上对此进行了测试，效果很好。不过，您可能需要对 CSS 进行一些修改以匹配您的站点。

You should consider using a base64 arrow image for this, one less request to the server. Feel free to use mine for this:
您应该考虑为此使用 base64 箭头图像，减少对服务器的请求。随意使用我的：
