sepia( )Īlters the colors in the element to be shifted toward shades of sepia tones (sepia is a reddish-brown color, defined by Wikipedia to be equivalent to #704214 or rgba(112,66,20) in the sRGB color space). A value of 0 leaves the element unchanged, and a value of 1 or 100% will result in a fully grayscale element. Note that for the first three of the four of the following functions, all of which accept either a or, negative values are not permitted: grayscale( )Īlters the colors in the element to be shifted toward shades of gray. This can be as simple as leaching out the colors, or as complex as shifting all the colors by way of an angle value. This next set of filter functions alter the colors present in the filtered element in some way. I’ve grouped these functions into a few broad categories for ease of understanding. Filters are applied to this input, and the final filtered result is then rendered to the display medium.Īll the values permitted are effectively functions, with the permitted value types for each being dependent on the function in question. The input image is a visual copy of the rendered element before it is filtered. Any HTML element can be filtered, and all graphic SVG elements can be filtered. The CSS specification talks of “input images” when discussing filter, but this doesn’t mean filter is only used on images. If the order were reversed, so too would be the order of application: the fully opaque element is burred, and the resulting blur made semi-transparent. Thus, given the declaration filter: opacity(0.5) blur(1px), the opacity is applied to the element, and the semi-transparent result is then blurred. The value syntax permits a comma-separated list of filter functions, with each filter applied in sequence. It shows our students that we care about them, the course, the content, and that we take pride in our craft.#Īll elements (in SVG, applies to all graphics elements and all container elements except the element) In an era where it seems like a lot of course content is created by robots, there is value in seeking out ways to add personalization and humanization to our content. These kinds of interactions may not contribute directly to students’ mastery of content or greatly impact curriculum alignment and assessment, but they truly add flair and impact to your presentation. And with that you should be able to start creating your own parallax effects with text overlay. bold) either in the RCE or in the HTML editor. You can customize your font size, family, color, and properties (e.g.
Play around with 100% if you’d like, but I would recommend some left and right padding if you do that, and don’t put to much text. For me, the min-width of 350px is ideal, and you can figure out the width that you would like, perhaps 50% or 75%. I suggest setting a width and a min-width. The next will be where your text sits and should have the class="overlay-text". I would definitely set the width to be 100%, and you can determine the height that you would like, set in pixels (e.g.
You’ll set your picture using inline CSS: style="background-image: url('YOUR IMAGE URL HERE'). You can also add the overlay-lighten or overlay-darken class if you would like. The next is your image with class="parallax". Both the parallax image and the overlay text will be within this You’ll start a with the class="overlay-content".
