使用 symfony 框架调整图像标签样式的最合适方法是什么。这是我的例子:
<?php echo link_to(image_tag('/design/fb.png'), 'https://www.facebook.com') ?>
如何设置 fb.png 图像的样式,例如我想使用margin-top: 5px;
.
好吧,这里有很多选择。
您可以通过检查AssetHelper.php
内部 symfony 来查看它们:
/**
* Returns an <img> image tag for the asset given as argument.
*
* <b>Options:</b>
* - 'absolute' - to output absolute file paths, useful for embedded images in emails
* - 'alt' - defaults to the file name part of the asset (capitalized and without the extension)
* - 'size' - Supplied as "XxY", so "30x45" becomes width="30" and height="45"
*
* <b>Examples:</b>
* <code>
* echo image_tag('foobar');
* => <img src="images/foobar.png" alt="Foobar" />
* echo image_tag('/my_images/image.gif', array('alt' => 'Alternative text', 'size' => '100x200'));
* => <img src="/my_images/image.gif" alt="Alternative text" width="100" height="200" />
* </code>
*
* @param string $source image asset name
* @param array $options additional HTML compliant <img> tag parameters
*
* @return string XHTML compliant <img> tag
* @see image_path
*/
function image_tag($source, $options = array())
所以,你可以直接整合style
属性:
<?php echo link_to(
image_tag(
'/design/fb.png',
array('style' => 'margin-top: 5px;')
),
'https://www.facebook.com'
) ?>
或者定义一个class
as 属性并class
在一个 css 文件中创建
<?php echo link_to(
image_tag(
'/design/fb.png',
array('class' => 'img-fb')
),
'https://www.facebook.com'
) ?>
你的CSS:
.img-fb {
margin-top: 5px;
}
