头文字从包装逃脱(Header text escapes from wrapper)

在移动设备上的标题文字从DIV包装逃脱。我该如何预防呢？它只有在还剩下2个字符发生。如果可能的话只能用纯CSS使它（如果需要的jQuery）。

HTML（Laravel材料叶片）

@section('content')
@if($builds)
    @foreach($builds as $result)
        <div class="col-md-4">
            <div class="builds">   
                <img src="{{ $result->icon }}" class="img-responsive" alt="Hero icon" />
                <div class="text">
                    <h2>{{ $result->name }} - {{ $result->build }}</h2>
                    <i><span class="usercolored">{{ $result->created_by }} </span>,{{ date('d-m-Y', strtotime($result->date)) }} <br /> {{ $result->views }} zobrazení</i><br />
                    <button class="btn btn-primary btn-md">Přejit na build</button>
                </div>               
            </div>
        </div>
    @endforeach
@else
    <p>Nic nenalezeno</p>
@endif
@endsection

CSS

.builds {
    box-shadow: 0 4px 8px 0 rgba(0,0,0,0.2);
    height: 191px;
    margin-top: 10px;
}

.builds h2{
    margin: 0;
}

.builds:hover {
    box-shadow: 0 8px 16px 0 rgba(0,0,0,0.2);
}

.builds img {
    width: 171px;
    height: 191px;
    float: left;
}

.builds .text {
    margin-left: 180px;
}

Answer 1:

.builds h2{
  word-wrap: break-word;
  //word-break: break-all;
}

我创建了一个例子让你了解它是如何工作的。例子是良好的内，将不适合比较小的容器，一个不同寻常的长字。

 div { width: 100px; border: 1px solid red; } /* word-wrap: break-word recently changed to overflow-wrap: break-word. */ .overflow { /* A long word/string will break in random places. A hyphen character will not be inserted. */ overflow-wrap: break-word; } /* A very long word WILL NOT start at the point it should start. It will be wrapped to next line and then being broken. */ .word-wrap { word-wrap: break-word; } /* Avery long word starts at the point it should start and it is being broken. */ .word-break { word-break: break-all; }

 Normal: <div>I am a text that 0123456789012345678901234567890123456789</div><br> overflow-wrap: break-word; <div class="overflow">I am a text 000001234567890123456789</div><br> word-wrap: break-word; <div class="word-wrap">I am a text 000001234567890123456789</div><br> word-break: break-all; <div class="word-break">I am a text 000001234567890123456789</div><br>
