Clear absolutely positioned elements with CSS possible?

由 此生再无相见时 提交于 2019-12-29 06:47:29
问题 Is there any way to clear absolutely positioned elements with CSS? I'm creating a page where I need each part of the site (section element) to be absolutely positioned, and I want to apply a footer with content below those elements. Tried to relatively position the header and footer to see if a total height would be taken into account but the footer still gets "trapped" underneath the section elements. Any ideas? <header style="position: relative;"></header> <div id="content" style="position:

How to clear all the md-input fields at once inside a md-form using an external button in Angular 2/2+/4

由 孤人 提交于 2019-12-25 11:53:56
问题 I want to clear all the fields inside a md-form at once using an external clear button like you do in normal HTML Forms. The problem with md-form is that it contains md-input fields instead of regular input fields. So the simple reset function won't trigger that. I've set the type of each field to 'search' that gives some kind of control but it's like u have to manually click and remove each value of the filed. I want to erase them all at once. Is there a proper way to to this? Thanks in

问题 I am making a list of blurbs with images that can be used anywhere throughout our site. I want it to be really flexible, not have a specified width, and work properly with no image and with different sizes of images. If the text for a block is longer than its image, I want the text not to wrap under the image. I made a fiddle of pretty much exactly how I want it. https://jsfiddle.net/4dbgnqha/1/ Now the problem is, our senior developer told me I can't use overflow:hidden to clear the float or
