css - 减少顶部行之间的差距

Question

我在让顶部间隙与元素之间左右间隙的距离相匹配时遇到问题。如何使顶部间隙变窄，使其与每个 Bootstrap 按钮的左右间隙一致？

html

    <div ng-controller="RecipeController">
    <div class="row">
    <div class="col-md-offset-5">
<form class="form-inline">
  <input ng-model="query" type="text" class="form-control"
    placeholder="Search Chicken Recipes" autofocus>
</form>

    <div class="row">

        <div ng-repeat="recipe in ChickenRecipes | limitTo: -16 | filter:query | orderBy: 'name' ">
            <div class="col-md-3">
                <div class="row top-buffer"> </div>

                <button class="btn btn-primary btn-lg" ng-click="open(recipe)"><img ng-src="{{recipe.image}}" alt="recipeImage" class="recipeImage"/><br>{{ recipe.name }}</button> <br />
            </div>  
        </div>

          </div>
    </div><!--end recipeController-->


</div><!--end container-->

Answer 1

检查以下代码。

.top-buffer {
   margin-top: 30px;
}

这会产生问题。
