如何在php中插入css代码？

Question

I know how to insert html code in php using print <<<HERE HERE; construction. It means I can insert a link to css file. But is it possible to insert css code itself?

Answer 1

There are a couple of ways you can achieve this.

Lets say you have an anchor tag <a href="..">My Href</a> and you want to add CSS to it based on certain instances.

You can easily echo that css into the anchor element like so:

<a <?php echo 'style="float: left;"'; ?> href="..">My Href</a>

The output would be: <a style="float: left" href="...">My Href</a>

You can do this with almost any HTML element.

Now let's say you have a predefined CSS class you would like to echo into an anchor tag element.

Let's say you have this CSS class in your stylesheet:

.floatLeft {
    float: left;
}

You can simply echo that class into the anchor element like so:

<a href="..." class="<?php echo 'floatLeft'; ?>">My Href</a>

Which the output of that would be:

<a href="..." class="floatLeft">My Href</a>
