Jquery mobile Jquery Mobile“可折叠集合”中的前2项在大屏幕上不对齐

此可折叠集合上最上面的两个项目将自身居中。有没有办法解决这个问题？ HTML都是一样的，所以我假设它是Jquery Mobile中的某个深层原因造成的。在我的手机上看起来不错。只是不在大屏幕上。注意，我复制了前两项-一旦它们在列表中排名第三，它们看起来就不错了。因此，与Jquery移动专家没有任何混淆-我确实在HTML中添加了这一行，以便在更大的屏幕上约束和集中所有内容：

<div style="max-width:600px;margin: 0 auto;">

我的问题与此无关-pageitems在前后都做了相同的操作

    <div data-role="collapsible-set">
        <div data-role="collapsible" data-theme="b" data-content-theme="e" >
            <h3>Branded Mobile Apps</h3>
            <img src="phonesbig.png"/>
            <p>With the REcake system you get native mobile apps for iPhone, Android, and iPad. The apps are branded to you and make it super easy for your clients to contact you. Keeping prospects is always a challenge and having YOUR app on their phone really helps that!</p>

            <h3>Lead Gen-Text, QR, and NFC</h3>
            <img src="daleresponse.png"/>
            <p>Text response is still the preferred method for mobile lead generation. Go ahead and try what the sign says and see what happens! Dale is an agent in Washington state and would love to hear from you. Our system allows these signs to be reusable- you just log in and change the MLS number and the sign works on the new property.  We can also show you how to get text leads from your print ads!  </p>
            <p>Our system also generates reusable QR codes that point to mobile property pages as well. These pages- like the one at <a href="http://rea.bz/kelly-6" target="new">rea.bz/kelly-6</a> give leads information about properties and also show them how to download your app.

            <h3>Agent Facebook App</h3>
            <img src="facebookapp.png"/>
            <p>Do you log into Facebook nearly every day? If so, then the REcake Facebook makes perfect sense for you. Your friends can stay right on Facebook and search for properties, contact you about the ones they like, save favorites, print flyers, map the properties, and more.</p>

        <div data-role="collapsible" data-theme="b" data-content-theme="e">
            <h3>Agent Branded Mobile Web</h3>
            <img src="personal.png"/>
            <p>In addition to our apps we provide a growing number of mobile web features. For instance you get branded mobile property pages for every property in the MLS. You also get a personal agent page that allows people to contact you very easily- for instance- <a href="http://rea.bz/kelly" target="new">rea.bz/kelly</a> </p>

因为下面的div位于可折叠集合之前。若你们移除它，桌面上的一切都会很好

<div class="content-secondary"></div>
