文字没有超过图像

Question

所以我正在制作一个需要在图像顶部设置字幕的图库/ imageshow，所以我有一部分工作，他们坐在图像上，但他们不会坐在图像上，但在与图像相同的位置最左边的图像。

html是图像的一部分和右边的包装等。

        <div id="wrapper">
        <div class="inner">
            <section id="mainProjects">
                <section id="headingProjects">
                    Projects
                </section>
                <section id="imagesProjects">
                    <a href="#"><section class="project"><img src="images/thumbnails/img1.jpg"/><section id="caption"><div id="text"><div id="title">Project 1</div ><div id="desc">this is some text about the project.</div></div></section></section></a>
                    <a href="#"><section class="project"><img src="images/thumbnails/img2.jpg"/><section id="caption"><div id="text"><div id="title">Project 1</div ><div id="desc">this is some text about the project.</div></div></section></section></a>
                    <a href="#"><section class="project"><img src="images/thumbnails/img3.jpg"/><section id="caption"><div id="text"><div id="title">Project 1</div ><div id="desc">this is some text about the project.</div></div></section></section></a>
                </section>
            </section>
        </div>
    </div>

这是CSS
