Building Fluid Web Interactions with CSS Animations and Transitions
Article Introduction：CSS animation and transition can improve the web interactive experience, but it needs to be used in moderation. 1. CSS transition is suitable for smooth state changes in properties such as color and size. It is often used for button hovering and menu expansion. Transition attributes, duration, easing functions and triggering conditions need to be specified; 2. CSS animation defines keyframes through @keyframes and is controlled by animation attributes. It is suitable for complex behaviors such as loop playback or delayed execution, such as rotation loading animation; 3. When using it, pay attention to the balance between performance and user experience, avoid excessive complex animations, give priority to the use of hardware acceleration attributes such as transform and opacity, and consider accessibility, and appropriately control the animation duration and device compatibility.

How to include CSS in an HTML document
Article Introduction：There are three common methods for introducing CSS in HTML documents: inline style, internal style sheet and external style sheet. 1. Inline styles are suitable for temporary modification or debugging, and are implemented by adding style attributes to HTML tags, but are not conducive to maintenance and unified management; 2. Internal style sheets are implemented by adding tags to them, suitable for small websites, with concentrated styles and no additional files loading, but they will be repeated when multiple pages are shared; 3. External style sheets are recommended, storing CSS in independent files and referenced through tags to separate HTML and CSS, which is convenient for maintenance and sharing of multiple pages. When using it, you need to pay attention to the correct path, tag location and browser cache issues.

How do I use the poster attribute to display a preview image before the video starts playing?
Article Introduction：Poster attributes are used in HTML5 to specify the preview image displayed before the video starts playing, which is implemented by adding an image URL to the tag. When using it, you need to ensure the correct path. The picture should be a high-quality keyframe screenshot to avoid blurred or overly dark images, and optimize the loading speed; some browsers or mobile devices may not display posters due to fast video loading, dynamic src or automatic playback restrictions; posters can be scaled through CSS, but the style is restricted directly. Reasonable selection and processing of posters can improve the user experience.

Animating elements with css transitions and keyframes
Article Introduction：The key to improving user experience in CSS animation is to choose transition and @keyframes reasonably. 1. Transition is suitable for simple state changes, such as button hover effect, which is achieved by defining attributes, duration, delay and speed curves; 2. @keyframes is suitable for complex animation sequences, such as loading animations, which controls the state of elements at different time points through multiple keyframes. Usage tips include: prioritizing the use of transform and opacity to improve performance, ensuring the initial consistency is consistent with the target state, and setting the ease function reasonably. Frequently asked questions: enable hardware acceleration in a timely manner and reduce nesting, check the property name and initial value when the transition does not take effect, and repeat animation playback can be performed through inf

How to create a progress bar in HTML?
Article Introduction：Use HTML tags to quickly add progress bars. The basic usage is to set the current progress and total progress through value and max attributes, if it means 70% complete; if value is not set, loading animation is displayed, and modern browsers are supported by default, but there may be differences in mobile or old versions; you can customize styles through CSS, such as adjusting color, height, and rounded corners. Different browsers need to use different pseudo-elements, such as::-webkit-progress-value is suitable for Chrome, while Firefox requires::-moz-progress-bar; if you need higher degrees of freedom, you can simulate the progress bar, the outer container on the structure controls the overall appearance, and the inner div controls the progress through width.
