问题描述
我正在为客户开发应用程序，并试图创建一个带有完全自定义图标的按钮.图标为30px x 30px，中间是透明的.
I am working on an app for a client and am trying to create a button with a completely custom icon. The icon is 30px x 30px and transparent in the middle.
使用此CSS代码，我几乎实现了我想要的:
I have almost achieved what I want using this css code:
/* info button override */
.ui-icon-info-page {
background: url(images/G_help_icon_round.png) 50% 50% no-repeat;
background-size: 30px 30px;
background-color: black;
}
但是在图标内部出现了一个黑色的细圆圈，并且图标图像似乎被切除了:
But there is a thin black circle that appears inside the icon, and also the icon image appears to be cut off:
我要删除此圆圈并防止显示图标?从被切断.另外，我希望问号是透明的，而不是黑色的，以显示下方导航栏的图像.但是，如果我尝试将背景色设置为透明，则该按钮将显示为完全白色:
I want to remove this circle and prevent the icon ? from being cut off. Also, I would like the question mark to be transparent instead of black, to show the image of the navigation bar beneath. If I try to set the background color to transparent though, the button appears entirely white:
我该怎么做?
更新:
我尝试应用此代码:
/* info button override */
.ui-icon-info-page {
background: url(help.png) 50% 50% no-repeat;
background-size: 30px 30px;
width: 30px;
height: 30px;
margin-top: -15px !important;
box-shadow: none;
-webkit-box-shadow: none;
}
并得到以下结果:
我可以通过调整顶部和左侧边距来移动图标，但是在以黑色圆圈为中心的框架之外，其边缘被切掉了:
I'm able to move the icon around by adjusting the top and left margins, but it's edges are cut off outside a frame centered on the black circle:
更新2:
这是我正在使用的按钮(请注意，这里是不可见的，因为它是白色背景上的白色按钮):
Here is the button I am using (Note that it is invisible here because it is a white button on a white background):
这是我用来加载按钮的html代码:
Here is the html code that I use to load the button:
<div data-role="header" data-position="fixed">
<div><img border="0" src="images/G_iphone_navbar_logo.png" style="display:inline;"/> </div>
<a href="index.html" data-icon="refresh" class="ui-btn-left" data-transition="fade" data-iconpos="notext" data-theme="a"></a>
<a href="info.html" data-icon="info-page" class="ui-btn-right" data-transition="flip" data-iconpos="notext" data-theme="a"></a>
</div>
推荐答案
这应该可以解决问题
/* info button override */
.ui-icon-info-page {
background: url(help.png) 50% 50% no-repeat;
background-size: 30px 30px;
width: 30px;
height: 30px;
margin-top: -15px !important;
box-shadow: none;
-webkit-box-shadow: none;
}
请确保在jquery移动CSS之后加载应用程序CSS文件.
Please ensure you are loading your application css file after jquery mobile css.
