如何设置有效的字体大小

一、从DW中h1字体大小设置

在网页设计过程中,H1标签通常都是作为页面的标题来使用的,因此其字体大小的设置相对于其他的标签来说,显得尤为重要。下面将针对DW软件中的字体大小设置做出详细的阐述。

1、进入DW软件后,打开”字符”面板,选中需要设置字体的标签。如果需要修改的是H1标签的字体大小,那么首先需要在”字符”面板中选中H1标签。然后,在下方的”属性”中找到”字号”选项。

<h1>代码示例</h1>

2、在”字号”选项中,用户可以使用鼠标滚轴或手动输入的方式来选择H1标签的字体大小。一般来说,网页设计师都建议在设置字体大小的时候,保证H1标签的字体大小在30px—35px之间,以便更好地符合网页设计的风格。

二、h1标签设置字体大小

和DW软件不同,我们在编写HTML代码的时候,也可以通过直接设置H1标签的字体大小来实现相应的效果。下面将介绍几种具体的方法:

1、使用style属性设置字体大小

<h1 style="font-size: 30px;">代码示例</h1>

其中,style="font-size: 30px;"是通过内联样式的方式来为H1标签设置字体大小的,30px为具体的字体大小。但是,这种方式不够灵活,同时也不便于修改和管理,因此网页设计中多采用CSS样式表的方式来管理各种样式。

2、使用CSS样式表设置字体大小

<head>
    <style type="text/css">
        h1{
            font-size: 30px;
        }
    </style>
</head>
<body>
    <h1>代码示例</h1>
</body>

在上述的代码中,我们使用了外部样式表的方式来设置H1标签的字体大小,其中的30px也可以根据实际需求进行修改。

三、Font-size:16px之外的尺寸

在进行网站开发时,我们也可以设置一些非常规的字体大小,以此为网站注入更多的个性化元素。下面将介绍三种在font-size:16px之外设置字体大小的方式:

1、使用em

em是相对于父元素字体大小的倍数,通常情况下1em等于16px。因此,如果需要设置字体大小为32px,可以使用2em:

<h1 style="font-size: 2em;">代码示例</h1>

2、使用rem

rem(root em)的特点是,无论在哪个层级下,它始终都是相对于根元素(html)的字体大小来设置。例如:

html{
    font-size: 16px;
}
h1{
    font-size: 2rem;// 32px
}

3、使用vw和vh

vw(viewport width)和vh(viewport height)是相对于视口宽度和高度的单位,其中1vw等于视口宽度的1%。这样,我们就可以用vw和vh来设置与视口宽度和高度相关的字体大小。例如:

h1{
    font-size: 5vw;
}

四、总结

在进行网页设计时,字体大小的正确设置能够对网站的视觉效果起到很大的影响,因此网页设计师需要掌握各种有效的设置方法。通过本文的介绍,相信大家已经对字体大小的设置方式有了更深入的了解。希望本文对大家有所帮助!
